ARID/BRIGHT DNA binding domain of lysine-specific demethylase KDM5C and KDM5D; This group includes KDM5C and KDM5D, both of which belong to the JARID subfamily within the JmjC proteins. KDM5C, also called histone demethylase JARID1C, Jumonji/ARID domain-containing protein 1C, protein SmcX, or protein Xe169, is a H3K4 trimethyl-histone demethylase that catalyzes demethylation of H3K4me3 and H3K4me2 to H3K4me1. It plays a role in neuronal survival and dendrite development. KDM5C defects are associated with X-linked mental retardation (XLMR). KDM5D, also called histocompatibility Y antigen (H-Y), histone demethylase JARID1D, Jumonji/ARID domain-containing protein 1D, or protein SmcY, is a male-specific antigen that shows a demethylase activity specific for di- and tri-methylated histone H3K4 (H3K4me3 and H3K4me2), and has a male-specific function as a histone H3K4 demethylase by recruiting a meiosis-regulatory protein, MSH5, to condensed DNA. KDM5D directly interacts with a polycomb-like protein Ring6a/MBLR, and plays a role in regulation of transcriptional initiation through H3K4 demethylation. Both KDM5C and KDM5D contain the catalytic JmjC domain, a JmjN domain, an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), a C5HC2 zinc finger, as well as two plant homeodomain (PHD) fingers.

PHD zinc finger; The plant homeodomain (PHD) finger is a C4HC3 zinc-finger-like motif found in nuclear proteins thought to be involved in epigenetics and chromatin-mediated transcriptional regulation. The PHD finger binds two zinc ions using the so-called 'cross-brace' motif and is thus structurally related to the RING finger and the FYVE finger. It is not yet known if PHD fingers have a common molecular function. Several reports suggest that it can function as a protein-protein interacton domain and it was recently demonstrated that the PHD finger of p300 can cooperate with the adjacent BROMO domain in nucleosome binding in vitro. Other reports suggesting that the PHD finger is a ubiquitin ligase have been refuted as these domains were RING fingers misidentified as PHD fingers.

JmjC domain, hydroxylase; The JmjC domain belongs to the Cupin superfamily. JmjC-domain proteins may be protein hydroxylases that catalyze a novel histone modification. This is confirmed to be a hydroxylase: the human JmjC protein named Tyw5p unexpectedly acts in the biosynthesis of a hypermodified nucleoside, hydroxy-wybutosine, in tRNA-Phe by catalysing hydroxylation.

ARID/BRIGHT DNA binding domain of lysine-specific demethylase 5B (KDM5B); KDM5B, also called cancer/testis antigen 31 (CT31), histone demethylase JARID1B, Jumonji/ARID domain-containing protein 1B (JARID1B), PLU-1, or retinoblastoma-binding protein 2 homolog 1 (RBP2-H1 or RBBP2H1A), is a member of the JARID subfamily within the JmjC proteins. It has a restricted expression pattern in the testis, ovary, and transiently in the mammary gland of the pregnant female and has been shown to be upregulated in breast cancer, prostate cancer, and lung cancer, suggesting a potential role in tumorigenesis. KDM5B acts as a histone demethylase that catalyzes the removal of trimethylation of lysine 4 on histone H3 (H3K4me3), induced by polychlorinated biphenyls (PCBs). It also mediates demethylation of H3K4me2 and H3K4me1. Moreover, KDM5B functions as a negative regulator of hematopoietic stem cell (HSC) self-renewal and progenitor cell activity. KDM5B has also been shown to interact with the DNA binding transcription factors BF-1 and PAX9, as well as TIEG1/KLF10 (transforming growth factor-beta inducible earlygene-1/Kruppel-like transcription factor 10), and possibly function as a transcriptional corepressor. KDM5B contains the catalytic JmjC domain, a JmjN domain, an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), a C5HC2 zinc finger, as well as three plant homeodomain (PHD) fingers.

ARID/BRIGHT DNA binding domain; Members of the recently discovered ARID (AT-rich interaction domain) family of DNA-binding proteins are found in fungi and invertebrate and vertebrate metazoans. ARID-encoding genes are involved in a variety of biological processes including embryonic development, cell lineage gene regulation and cell cycle control. Although the specific roles of this domain and of ARID-containing proteins in transcriptional regulation are yet to be elucidated, they include both positive and negative transcriptional regulation and a likely involvement in the modification of chromatin structure. The basic structure of the ARID domain domain appears to be a series of six alpha-helices separated by beta-strands, loops, or turns, but the structured region may extend to an additional helix at either or both ends of the basic six. Based on primary sequence homology, they can be partitioned into three structural classes: Minimal ARID proteins that consist of a core domain formed by six alpha helices; ARID proteins that supplement the core domain with an N-terminal alpha-helix; and Extended-ARID proteins, which contain the core domain and additional alpha-helices at their N- and C-termini.

PHD finger 1 found in Lysine-specific demethylase 5A (KDM5A); KDM5A (also termed Histone demethylase JARID1A, Jumonji/ARID domain-containing protein 1A, or Retinoblastoma-binding protein 2 (RBBP-2 or RBP2)) was originally identified as a retinoblastoma protein (Rb)-binding partner and its inactivation may be important for Rb to promote differentiation. It is involved in transcription through interacting with TBP, p107, nuclear receptors, Myc, Sin3/HDAC, Mad1, RBP-J, CLOCK and BMAL1. KDM5A functions as a trimethylated histone H3 lysine 4 (H3K4me3) demethylase that belongs to the JARID subfamily within the JmjC proteins. It also displays DNA-binding activities that can recognize the specific DNA sequence CCGCCC. KDM5A contains the catalytic JmjC domain, JmjN, the BRIGHT domain, which is an AT-rich interacting domain (ARID), and a Cys5HisCys2 zinc finger, as well as three plant homeodomain (PHD) fingers. This model corresponds to the first PHD finger.

ARID/BRIGHT DNA binding domain family; The AT-rich interaction domain (ARID) family of transcription factors, found in a broad array of organisms from fungi to mammals, is characterized by a highly conserved, helix-turn-helix DNA binding domain that binds to the major groove of DNA. The ARID domain, also called BRIGHT, was first identified in the mouse B-cell-specific transcription factor Bright and in the product of the dead ringer (dri) gene of Drosophila melanogaster. ARID family members are implicated in normal development, differentiation, cell cycle regulation, transcriptional activation and chromatin remodeling. Different family members exhibit different DNA-binding properties. Drosophila Dri, mammalian ARID3A/3B/3C and ARID5A/5B, selectively bind AT-rich sites. However, ARID1A/1B, Drosophila Osa, yeast SWI1, ARID2, ARID4A/4B, JARID1A/1B/1C/1D, and JARID2, bind DNA without sequence specificity.

It alters the remodeling properties of the ATPase motor protein sucrose nonfermenting-2 homolog (SNF2H). Moreover, BAZ1A and its complexes play important roles in DNA double-strand break (DSB) repair. It is essential for averting improper gene expression during spermatogenesis. It also regulates transcriptional repression of vitamin D3 receptor-regulated genes. BAZ1A contains a WAC motif, a DDT domain, BAZ 1 and BAZ 2 motifs, a WAKZ (WSTF/Acf1/KIAA0314/ZK783.4) motif, a plant homeodomain (PHD) finger, and a bromodomain.

PHD finger found in bromodomain adjacent to zinc finger domain protein 2A (BAZ2A) and 2B (BAZ2B); BAZ2A, also termed transcription termination factor I-interacting protein 5 (TTF-I-interacting protein 5, or Tip5), or WALp3, is an epigenetic regulator. It has been implicated in epigenetic rRNA gene silencing, as the large subunit of the SNF2h-containing chromatin-remodeling complex NoRC that induces nucleosome sliding in an ATP- and histone H4 tail-dependent fashion. BAZ2A has also been shown to be broadly overexpressed in prostate cancer, to regulate numerous protein-coding genes and to cooperate with EZH2 (enhancer of zeste homolog 2) to maintain epigenetic silencing at genes repressed in prostate cancer metastasis. Its overexpression is tightly associated with a prostate cancer subtype displaying CpG island methylator phenotype (CIMP) in tumors and with prostate cancer recurrence in patients. BAZ2B, also termed WALp4, is a bromodomain-containing protein whose biological role is still elusive. It shows high sequence similarly with BAZ2A. Both BAZ2A and BAZ2B contain a TAM (TIP5/ARBP/MBD) domain, a DDT domain, four AT-hooks, BAZ 1 and BAZ 2 motifs, a WAKZ (WSTF/Acf1/KIAA0314/ZK783.4) motif, a plant homeodomain (PHD) finger, and a bromodomain. BAZ2B also harbors an extra Apolipophorin-III like domain in its N-terminal region.

PHD finger 1 found in Schizosaccharomyces pombe Lid2 complex component Lid2p and similar proteins; Lid2p is a trimethyl H3K4 (H3K4me3) demethylase responsible for H3K4 hypomethylation in heterochromatin. It interacts with the histone lysine-9 methyltransferase, Clr4, through the Dos1/Clr8-Rik1 complex, and mediates H3K9 methylation and small RNA production. It also acts cooperatively with the histone modification enzymes Set1 and Lsd1 and plays an essential role in cross-talk between H3K4 and H3K9 methylation in euchromatin. Lid2p contains a JmjC domain, three PHD fingers and a JmjN domain. This model corresponds to the first PHD finger.

PHD finger 5 found in Histone-lysine N-methyltransferase 2C (KMT2C) and PHD finger 4 found in KMT2D; KMT2C, also termed myeloid/lymphoid or mixed-lineage leukemia protein 3 (MLL3), or homologous to ALR protein, is a histone H3 lysine 4 (H3K4) lysine methyltransferase that functions as a circadian factor contributing to genome-scale circadian transcription. It is a component of a large complex that acts as a coactivator of multiple transcription factors, including the bile acid (BA)-activated nuclear receptor, farnesoid X receptor (FXR), a critical player in BA homeostasis. The MLL3 complex is essential for p53 transactivation of small heterodimer partner (SHP). KMT2C is also a part of activating signal cointegrator-2 (ASC-2)-containing complex (ASCOM) that contains the transcriptional coactivator nuclear receptor coactivator 6 (NCOA6), KMT2C and its paralog MLL4. The ASCOM complex is critical for nuclear receptor (NR) activation of bile acid transporter genes and is down regulated in cholestasis. KMT2D, also termed ALL1-related protein (ALR), is encoded by the gene that was named MLL4, a fourth human homolog of Drosophila trithorax, located on chromosome 12. It enzymatically generates trimethylated histone H3 Lysine 4 (H3K4me3). It plays an essential role in differentiating the human pluripotent embryonal carcinoma cell line NTERA-2 clone D1 (NT2/D1) stem cells by activating differentiation-specific genes, such as HOXA1-3 and NESTIN. KMT2D is also a part of ASCOM. Both KMT2C and KMT2D contain the catalytic domain SET, several plant homeodomain (PHD) fingers, extended PHD (ePHD) fingers, Cys2HisCys5HisCys2His, a RING finger, an HMG (high-mobility group)-binding motif, and two FY-rich regions. This model corresponds to the fifth PHD finger of KMT2C and the fourth PHD finger of KMT2D.

PHD finger 2 found in class II Chromodomain-Helicase-DNA binding (CHD) proteins; Class II CHD proteins includes chromodomain-helicase-DNA-binding protein CHD3, CHD4, and CHD5, which are nuclear and ubiquitously expressed chromatin remodelling ATPases generally associated with histone deacetylases (HDACs). They are involved in DNA Double Strand Break (DSB) signaling, DSB repair and/or p53-dependent pathways such as apoptosis and senescence, as well as in the maintenance of genomic stability, and/or cancer prevention. They function as subunits of the Nucleosome Remodelling and Deacetylase (NuRD) complex, which is generally associated with gene repression, heterochromatin formation, and overall chromatin compaction. In contrast to the class I CHD enzymes (CHD1 and CHD2), class II CHD proteins lack identifiable DNA-binding domains, but possess a C-terminal coiled-coil region. Moreover, in addition to the tandem chromodomains and a helicase domain, they all harbor tandem plant homeodomain (PHD) zinc fingers involved in the recognition of methylated histone tails. This model corresponds to the second PHD finger.

BAZ1B, also termed Tyrosine-protein kinase BAZ1B, or Williams syndrome transcription factor (WSTF), or Williams-Beuren syndrome chromosomal region 10 protein, Williams-Beuren syndrome chromosomal region 9 protein, or WALp2, is a multifunctional protein implicated in several nuclear processes, including replication, transcription, and the DNA damage response. BAZ1B/WSTF, together with the imitation switch (ISWI) ATPase, forms a WSTF-ISWI chromatin remodeling complex (WICH), which transiently associates with the human inactive X chromosome (Xi) during late S-phase prior to BRCA1 and gamma-H2AX. Moreover, BAZ1B/WSTF, SNF2h, and nuclear myosin 1 (NM1) forms the chromatin remodeling complex B-WICH that is involved in regulating rDNA transcription.

PHD finger found in ubiquitin-like PHD and RING finger domain-containing protein UHRF1 and UHRF2; UHRF1 is a unique chromatin effector protein that integrates the recognition of both histone PTMs and DNA methylation. It is essential for cell proliferation and plays a critical role in the development and progression of many human carcinomas, such as laryngeal squamous cell carcinoma (LSCC), gastric cancer (GC), esophageal squamous cell carcinoma (ESCC), colorectal cancer, prostate cancer, and breast cancer. UHRF1 acts as a transcriptional repressor through its binding to histone H3 when it is unmodified at Arg2. Its overexpression in human lung fibroblasts results in downregulation of expression of the tumour suppressor pRB. It also plays a role in transcriptional repression of the cell cycle regulator p21. Moreover, UHRF1-dependent repression of transcription factors can facilitate the G1-S transition. It interacts with Tat-interacting protein of 60 kDa (TIP60) and induces degradation-independent ubiquitination of TIP60. It is also an N-methylpurine DNA glycosylase (MPG)-interacting protein that binds MPG in a p53 status-independent manner in the DNA base excision repair (BER) pathway. In addition, UHRF1 functions as an epigenetic regulator that is important for multiple aspects of epigenetic regulation, including maintenance of DNA methylation patterns and recognition of various histone modifications. UHRF2 was originally identified as a ubiquitin ligase acting as a small ubiquitin-like modifier (SUMO) E3 ligase that enhances zinc finger protein 131 (ZNF131) SUMOylation but does not enhance ZNF131 ubiquitination. It also ubiquitinates PCNP, a PEST-containing nuclear protein. Moreover, UHRF2 functions as a nuclear protein involved in cell-cycle regulation and has been implicated in tumorigenesis. It interacts with cyclins, CDKs, p53, pRB, PCNA, HDAC1, DNMTs, G9a, methylated histone H3 lysine 9, and methylated DNA. It interacts with the cyclin E-CDK2 complex, ubiquitinates cyclins D1 and E1, induces G1 arrest, and is involved in the G1/S transition regulation. Furthermore, UHRF2 is a direct transcriptional target of the transcription factor E2F-1 in the induction of apoptosis. It recruits HDAC1 and binds to methyl-CpG. UHRF2 also participates in the maturation of Hepatitis B virus (HBV) by interacting with the HBV core protein and promoting its degradation. Both UHRF1 and UHRF2 contain an N-terminal ubiquitin-like domain (UBL), a tandem Tudor domain (TTD), a plant homeodomain (PHD) finger, a SET- and RING-associated (SRA) domain, and a C-terminal RING finger.

It inhibits LSD1-mediated histone demethylation in vitro. PHF21A is predominantly present in the central nervous system and spermatogenic cells and is one of the six components of BRAF-HDAC complex (BHC) involved in REST-dependent transcriptional repression of neuron-specific genes in non-neuronal cells. It acts as a scaffold protein in BHC in neuronal as well as non-neuronal cells and also plays a role in spermatogenesis. PHF21A contains a C-terminal plant homeodomain (PHD) finger that is responsible for the binding directly to each of five other components of BHC, and of organizing BHC mediating transcriptional repression.

ARID/BRIGHT DNA binding domain of AT-rich interactive domain-containing proteins ARID5A, ARID5B, and similar proteins; This subfamily contains ARID5A and its paralog ARID5B. ARID5A, also called modulator recognition factor 1 (MRF-1), is an estrogen receptor alpha (ER alpha)-interacting protein that is expressed abundantly in cardiovascular tissues and suppresses ER alpha-induced transactivation. It also plays an important role in the promotion of inflammatory processes and autoimmune diseases. ARID5B, also called MRF1-like protein or modulator recognition factor 2 (MRF-2), is a DNA-binding protein that directly interacts with plant homeodomain (PHD) finger 2 (PHF2) to form a protein kinase A (PKA)-dependent PHF2-ARID5B histone H3K9Me2 demethylase complex. It also functions as a transcriptional co-regulator for the transcription factor sex determining region Y (SRY)-box protein 9 (Sox9) and promotes chondrogenesis through histone modification. Moreover, ARID5B is highly expressed in the cardiovascular system and may play essential roles in the phenotypic change of smooth muscle cells (SMCs) through its regulation of SMC differentiation. Both ARID5A and ARID5B contain an AT-rich DNA-interacting domain (ARID, also known as BRIGHT).

ARID/BRIGHT DNA binding domain of yeast SWI/SNF chromatin-remodeling complex subunit Swi1p and similar proteins; Saccharomyces cerevisiae Swi1p, also called SWI/SNF chromatin-remodeling complex subunit SWI1, regulatory protein GAM3, or transcription regulatory protein ADR6, is a transcription regulatory protein that is a subunit of the SWI/SNF complex, which plays critical roles in the regulation of gene transcription and expression. It can exist as a prion, [SWI(+)], which demonstrates a link between prionogenesis and global transcriptional regulation. Swi1p contains an AT-rich DNA-interacting domain (ARID, also known as BRIGHT) that binds DNA nonspecifically. This subfamily also includes Schizosaccharomyces pombe SWI/SNF chromatin-remodeling complex subunit sol1 (sol1p, also known as switch one-like protein). sol1p is a homolog of S. cerevisiae Swi1p and is also a part of SWI/SNF chromatin-remodeling complex.

ARID/BRIGHT DNA binding domain of AT-rich interactive domain-containing protein 3C (ARID3C) and similar proteins; ARID3C, also called Brightlike, is a new ARID3 family transcription factor that co-activates ARID3A-mediated immunoglobulin gene transcription. It also functions as a potential regulator of early events in B cell antigen receptor (BCR) signaling. ARID3C contains an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), a SUMO-I conjugation (SUMO) motif and a multifunctional homomerization/nuclear export REKLES domain, which consists of two subdomains: a modestly conserved N-terminal REKLES alpha and a highly conserved (among ARID3 orthologous proteins) C-terminal REKLES beta.

ARID/BRIGHT DNA binding domain of AT-rich interactive domain-containing protein 3B (ARID3B) and similar proteins; ARID3B, also called Bright and dead ringer protein, or Bright-Dri-like protein (Bdp), is a DNA binding protein involved in cellular immortalization, epithelial-mesenchymal transition (EMT), and tumorigenesis. Its expression is differentially regulated in normal and malignant tissues. It is required for heart development by regulating the motility and differentiation of heart progenitors. ARID3B is overexpressed in neuroblastoma and ovarian cancer. It acts as a novel target with roles in cell motility in breast cancer cells, promotes migration of mouse embryo fibroblasts (MEFs) and breast cancer cells, and induces tumor necrosis factor alpha (TNFalpha)-mediated apoptosis. ARID3B contains an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), a SUMO-I conjugation (SUMO) motif and a multifunctional homomerization/nuclear export REKLES domain, which consists of two subdomains: a modestly conserved N-terminal REKLES alpha and a highly conserved (among ARID3 orthologous proteins) C-terminal REKLES beta.
