Extended PHD finger found in protein AF-10 and similar proteins; The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model includes the ePHD finger of AF-10. AF-10, also termed ALL1 (acute lymphoblastic leukaemia)-fused gene from chromosome 10 protein, is a transcription factor encoded by gene AF10, a translocation partner of the MLL (mixed-lineage leukaemia) oncogene in leukaemia. AF-10 has been implicated in the development of leukemia following chromosomal rearrangements between the AF10 gene and one of at least two other genes, MLL and CALM. It plays a key role in the survival of uncommitted hematopoietic cells. Moreover, AF-10 functions as a follistatin-related gene (FLRG)-interacting protein. The interaction with FLRG enhances AF10-dependent transcription. It interacts with human counterpart of the yeast Dot1, hDOT1L, and may act as a bridge for the recruitment of hDOT1L to the genes targeted by MLL-AF10. It also interacts with the synovial sarcoma associated protein SYT protein and may play a role in synovial sarcomas and acute leukemias. AF-10 contains an N-terminal plant homeodomain (PHD) finger followed by this non-canonical ePHD finger.

coiled coil domain of ALL1-Fused gene from chromosome 10 protein (AF10) and similar proteins; This family includes AF10 (ALL1-Fused gene from chromosome 10 protein) which is one of mixed-lineage leukemia 1 (MLL1)-fusion partners that function in acute myeloid leukemia (ALL). Aberration of the mixed-lineage leukemia (MLL) gene is implicated in acute leukemia; chromosomal translocations of MLL1 generate oncogenic chimeric proteins, containing the non-catalytic N-terminal portion of MLL1 fused with many partners such as AF10. The MLL-AF10 fusion oncoprotein recruits DOT1L (disruptor of telomeric-silencing 1-like) to the homeobox A. The aberrant recruitment of DOT1L, a histone methyltransferase that methylates H3 lysine residues (H3K79), by MLL fusions and the resulting H3K79 methylation are thought to affect gene expression by altering chromatin accessibility. AF10 and DOT1L interact through their coiled coil domains.

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.

This model includes the ePHD finger of AF-17. AF-17, also termed ALL1-fused gene from chromosome 17 protein, is encoded by gene AF17 that has been identified in hematological malignancies as a translocation partner of the mixed lineage leukemia gene MLL. It is a putative transcription factor that may play a role in multiple signaling pathways. It is involved in chromatin-mediated gene regulation mechanisms. It functions as a component of the multi-subunit Dot1 complex (Dotcom) and plays a role in the Wnt/Wingless signaling pathway. It also seems to be a downstream target of the beta-catenin/T-cell factor pathway, and participates in G2-M progression. Moreover, it may function as an important regulator of ENaC-mediated Na+ transport and thus blood pressure. AF-17 contains an N-terminal plant homeodomain (PHD) finger followed by a non-canonical ePHD finger.

Extended PHD finger found in Jumonji domain-containing protein 2B (JMJD2B); The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model includes the ePHD finger of JMJD2B. JMJD2B, also termed lysine-specific demethylase 4B (KDM4B), or JmjC domain-containing histone demethylation protein 3B (JHDM3B), specifically antagonizes the trimethyl group from H3K9 in pericentric heterochromatin and reduces H3K36 methylation in mammalian cells. It plays an essential role in the growth regulation of cancer cells by modulating the G1-S transition and promotes cell-cycle progression through the regulation of cyclin-dependent kinase 6 (CDK6). It interacts with heat shock protein 90 (Hsp90) and its stability can be regulated by Hsp90. JMJD2B also functions as a direct transcriptional target of p53, which induces its expression through promoter binding. Moreover, JMJD2B expression can be controlled by hypoxia-inducible factor 1alpha (HIF1alpha) in colorectal cancer and estrogen receptor alpha (ERalpha) in breast cancer. It is also involved in bladder, lung, and gastric cancer. JMJD2B contains jmjN and jmjC domains in the N-terminal region, followed by a canonical PHD finger, this non-canonical ePHD finger, and a Tudor domain.

Extended PHD finger found in protein Jade-1 and similar proteins; The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model includes the ePHD finger of Jade-1. Jade-1, also termed PHD finger protein 17 (PHF17), is a novel binding partner of von Hippel-Lindau (VHL) tumor suppressor Pvhl, a key regulator of cellular oxygen sensing pathway. It is highly expressed in renal proximal tubules. Jade-1 functions as an essential regulator of multiple cell signaling pathways. It may be involved in the Serine/threonine kinase AKT/AKT1 pathway during renal cancer pathogenesis and normally prevents renal epithelial cell proliferation and transformation. It also acts as a pro-apoptotic and growth suppressive ubiquitin ligase to inhibit canonical Wnt downstream effector beta-catenin for proteasomal degradation and ASA transcription factor associated with histone acetyltransferase activity and with increased abundance of cyclin-dependent kinase inhibitor p21. Moreover, Jade-1 is required for ING4 and ING5 to associate with histone acetyltransferase (HAT) HBO1 and Eaf6 to form a HBO1 complex, and plays a role in epithelial cell regeneration. It has also been identified as a novel component of the nephrocystin protein (NPHP) complex and interacts with the ciliary protein nephrocystin-4 (NPHP4). Jade-1 contains a canonical plant homeodomain (PHD) finger followed by this non-canonical ePHD finger, both of which are zinc-binding motifs.

Extended PHD finger found in retinoic acid-induced protein 1 (RAI1), transcription factor 20 (TCF-20) and similar proteins; The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model includes the C-terminal ePHD/ADD (ATRX-DNMT3-DNMT3L) domain of RAI1 and TCF-20. RAI1, a homolog of stromelysin-1 PDGF (platelet-derived growth factor)-responsive element-binding protein (SPBP, also termed TCF-20), is a chromatin-binding protein implicated in the regulation of gene expression. TCF-20 is involved in transcriptional activation of the MMP3 (matrix metalloprotease 3) promoter. It also functions as a transcriptional co-regulator that enhances or represses the transcriptional activity of certain transcription factors/cofactors, such as specificity protein 1 (Sp1), E twenty-six 1 (Ets1), paired box protein 6 (Pax6), small nuclear RING-finger (SNURF)/RNF4, c-Jun, androgen receptor (AR) and estrogen receptor alpha (ERalpha). Both RAI1 and TCF-20 are strongly enriched in chromatin in interphase HeLa cells, and display low nuclear mobility, and have been implicated in Smith-Magenis syndrome and Potocki-Lupski syndrome.
