Seven in absentia protein family; The seven in absentia (sina) gene was first identified in Drosophila. The Drosophila Sina protein is essential for the determination of the R7 pathway in photoreceptor cell development: the loss of functional Sina results in the transformation of the R7 precursor cell to a non- neuronal cell type. The Sina protein contains an N-terminal RING finger domain pfam00097. Through this domain, Sina binds E2 ubiquitin-conjugating enzymes (UbcD1) Sina also interacts with Tramtrack (TTK88) via PHYL. Tramtrack is a transcriptional repressor that blocks photoreceptor determination, while PHYL down-regulates the activity of TTK88. In turn, the activity of PHYL requires the activation of the Sevenless receptor tyrosine kinase, a process essential for R7 determination. It is thought that thus Sina targets TTK88 for degradation, therefore promoting the R7 pathway. Murine and human homologs of Sina have also been identified. The human homolog Siah-1 also binds E2 enzymes (UbcH5) and through a series of physical interactions, targets beta-catenin for ubiquitin degradation. Siah-1 expression is enhanced by p53, itself promoted by DNA damage. Thus this pathway links DNA damage to beta-catenin degradation. Sina proteins, therefore, physically interact with a variety of proteins. The N-terminal RING finger domain that binds ubiquitin conjugating enzymes is described in pfam00097, and does not form part of the alignment for this family. The remainder C-terminal part is involved in interactions with other proteins, and is included in this alignment. In addition to the Drosophila protein and mammalian homologs, whose similarity was noted previously, this family also includes putative homologs from Caenorhabditis elegans, Arabidopsis thaliana. : Pssm-ID: 460824 [Multi-domain] Cd Length: 198 Bit Score: 348.05 E-value: 4.93e-122

RING finger (Really Interesting New Gene) domain and U-box domain superfamily; The RING finger is a specialized type of Zn-finger of 40 to 60 residues that binds two atoms of zinc. It is defined by the "cross-brace" motif that chelates zinc atoms by eight amino acid residues, typically Cys or His, arranged in a characteristic spacing. Canonical RING motifs have been categorized into two major subclasses, RING-HC (C3HC4-type) and RING-H2 (C3H2C3-type), according to their Cys/His content. There are also many variants of RING fingers: some have different Cys/His patterns while some lack a single Cys or His residue at typical Zn ligand positions (the fourth or eighth zinc ligand is prevalently exchanged for an Asp, which can indeed chelate Zn in a RING finger as well). C4C4-, C3HC3D-, C2H2C4-, and C3HC5-type RING fingers are closely related to RING-HC fingers. In contrast, C4HC3- (RING-CH alias RINGv), C3H3C2-, C3H2C2D-, C3DHC3-, and C4HC2H-type RING fingers are more closely related to RING-H2 fingers. However, not all RING finger-containing proteins display regular RING finger features, and the RING finger family has turned out to be multifarious. The degenerate RING fingers of the Siz/PIAS RING (SP-RING) family proteins and sporulation protein RMD5, are characterized by lacking the second, fifth, and sixth Zn2+ ion-coordinating residues. They bind only one Zn2+ ion. On the other hand, the RING fingers of the human APC11 and RBX1 proteins can bind a third Zn atom since they harbor four additional Zn ligands. U-box is a modified form of the RING finger domain that lacks metal chelating Cys and His residues. It resembles the cross-brace RING structure consisting of three beta-sheets and a single alpha-helix, which would be stabilized by salt bridges instead of chelated metal ions. U-box proteins are widely distributed among eukaryotic organisms and show a higher prevalence in plants than in other organisms. RING finger/U-box-containing proteins are a group of diverse proteins with a variety of cellular functions, including oncogenesis, development, viral replication, signal transduction, the cell cycle and apoptosis. Many of them are ubiquitin-protein ligases (E3s) that serve as scaffolds for binding to ubiquitin-conjugating enzymes (E2s, also referred to as ubiquitin carrier proteins or UBCs) in close proximity to substrate proteins, which enable efficient transfer of ubiquitin from E2 to the substrates.

Seven in absentia (Sina) protein family, C-terminal substrate binding domain; composed of the Drosophila Sina protein, the mammalian Sina homolog (Siah), the plant protein SINAT5, and similar proteins. Sina, Siah and SINAT5 are RING-containing proteins that function as E3 ubiquitin ligases, acting either as single proteins or as a part of multiprotein complexes. Sina is expressed in many cells in the developing eye but is essential specifically for R7 photoreceptor cell development. Sina cooperates with Phyllopod (Phyl), Ebi and the E2 ubiquitin-conjugating enzyme Ubcd1 to catalyze the ubiquitination and subsequent degradation of Tramtrack (Ttk88); Ttk88 is a transcriptional repressor that blocks photoreceptor differentiation. Similarly, the mammalian homologue Siah1 cooperates with SIP (Siah-interacting protein), Ebi and the adaptor protein Skp1, to target beta-catenin for ubiquitination and degradation via a p53-dependent mechanism. SINAT5 targets NAC1 for ubiquitin-mediated degradation resulting in the downregulation of auxin, a hormone that controls many aspects of plant development. Other targets of Sina family proteins include c-Myb, synaptophysin, group 1 glutamate receptors, promyelocytic leukemia protein, alpha-synuclein, synphilin-1 and alpha-ketoglutarate dehydrogenase, among others. Sina proteins also bind proteins that are not targets for ubiquitination such as Phyl, adenomatous polyposis coli, VAV, BAG-1 and Dab-1. Siah binds to a consensus motif, PXAXVXP, which is present in Siah-binding proteins. Siah is a dimeric protein consisting of an N-terminal RING domain, two zinc finger motifs and a C-terminal substrate-binding domain (SBD); this SBD contains an eight-stranded antiparallel beta-sandwich fold similar to the MATH (meprin and TRAF-C homology) domain.

RING finger, HC subclass, found in seven in absentia homolog 2 (SIAH2) and similar proteins; SIAH2 is an E3 ubiquitin-protein ligase that contributes to proteasome-mediated degradation of multiple targets in numerous cellular processes. It targets the ubiquitylation and degradation of tumor necrosis factor receptor-associated factor 2 (TRAF2) under stress conditions, which is required for the cell to commit to undergoing apoptosis. It is, therefore, a key regulator of TRAF2-dependent signaling in response to tumor necrosis factor-alpha (TNF-alpha) treatment and UV irradiation. SIAH2 modulates the polyubiquitination of G protein pathway suppressor 2 (GPS2), and targets it for proteasomal degradation. It is also a regulator of NF-E2-related factor 2 (Nrf2), a key regulator of cellular oxidative response, and contributes to the degradation of Nrf2 irrespective of its phosphorylation status. Moreover, SIAH2 contributes to castration-resistant prostate cancer (CRPC) by regulation of androgen receptor (AR) transcriptional activity. It enhances AR transcriptional activity and prostate cancer cell growth. Its stability can be regulated by AKR1C3. SIAH2 also inhibits tyrosine kinase-2 (TYK2)-STAT3 signaling in lung carcinoma cells. Furthermore, SIAH2 regulates obesity-induced adipose tissue inflammation by altering peroxisome proliferator-activated receptor gamma (PPAR gamma) protein levels and selectively regulating PPAR gamma activity. It also functions as a regulator of the nuclear hormone receptor RevErbalpha (Nr1d1) stability and rhythmicity, and overall circadian oscillator function. In addition, SIAH2 is an essential component of the hypoxia response Hippo signaling pathway and has been implicated in normal development and tumorigenesis. It modulates the hypoxia pathway upstream of hypoxia-induced transcription factor subunit HIF-1alpha, and therefore may play an important role in angiogenesis in response to hypoxic stress in endothelial cells. It also stimulates transcriptional coactivator YAP1 by destabilizing serine/threonine-protein kinase LATS2, a critical component of the Hippo pathway, in response to hypoxia. Meanwhile, SIAH2 is involved in regulation of tight junction integrity and cell polarity under hypoxia, through its regulation of apoptosis-stimulating proteins of p53 subunit 2 (ASPP2) stability. SIAH2 contains an N-terminal C3HC4-type RING-HC finger, two zinc-finger subdomains, and a C-terminal tumor necrosis factor (TNF) receptor associated factor (TRAF)-like substrate-binding domain (SBD) responsible for dimer formation.

RING finger, HC subclass, found in seven in absentia homolog 1 (SIAH1) and similar proteins; SIAH1, also known as Siah-1a, is an inducible E3 ubiquitin-protein ligase that contributes to proteasome-mediated degradation of multiple targets in numerous cellular processes including apoptosis, tumor suppression, cell cycle, axon guidance, transcription regulation, and tumor necrosis factor signaling. SIAH1 functions as a scaffolding protein and interacts with a variety of different substrates for ubiquitination and subsequent degradation. It regulates the oncoprotein p34SEI-1 polyubiquitination and its subsequent degradation in a p53-dependent manner, which mediates p53 preferential vitamin C cytotoxicity. It targets the nonreceptor tyrosine kinase activated Cdc42-associated kinase 1 (ACK1), a valid target in cancer therapy, for ubiquitinylation and proteasomal degradation. It also interacts with KLF10 and targets it for degradation. The CDK2 phosphorylation-mediated KLF10 dissociation from SIAH1 is linked to cell cycle progression. Moreover, SIAH1 is downregulated and associated with apoptosis and invasion in human breast cancer. It targets TAp73, a homolog of the tumor suppressor p53, for degradation. It is suppressed by hypoxia-inducible factor 1-alpha (HIF-1alpha) under hypoxic conditions to regulate TAp73 levels. It also promotes the migration and invasion of human glioma cells by regulating HIF-1alpha signaling under hypoxia. Furthermore, SIAH1 forms a protein complex with glyceraldehyde-3-phosphate dehydrogenase (GAPDH). The apoptosis signal-regulating kinase 1 (ASK1) functions as an activator of the GAPDH-Siah1 stress-signaling cascade. It also plays an important role in ethanol-induced apoptosis in neural crest cells (NCCs). SIAH1 contains an N-terminal C3HC4-type RING-HC finger, two zinc-finger subdomains, and a C-terminal tumor necrosis factor (TNF) receptor associated factor (TRAF)-like substrate-binding domain (SBD) responsible for dimer formation.

RING finger, HC subclass, found in Drosophila melanogaster protein Seven-in-Absentia (sina) and its homologs; This subfamily includes the Drosophila melanogaster protein Seven-in-Absentia (sina), its mammalian orthologs, SIAH1 and SIAH2, plant SINA-related proteins, and similar proteins. Sina plays an important role in the phyllopod-dependent degradation of the transcriptional repressor tramtrack to allow the formation of the R7 photoreceptor in the developing eye of Drosophila melanogaster. Both SIAH1 and SIAH2 are E3 ubiquitin-protein ligases, mediating the ubiquitinylation and subsequent proteasomal degradation of biologically important target proteins that regulate general functions, such as cell cycle control, apoptosis, and DNA repair. They are inducible by the tumor suppressor and transcription factor p53. SIAH2 can also be regulated by sex hormones and cytokine signaling. Moreover, they share high sequence similarity, but possess contrary roles in cancer, with SIAH1 more often acting as a tumor suppressor while SIAH2 functions as a proto-oncogene. Plant SINAT1-5 are putative E3 ubiquitin ligases involved in the regulation of stress responses. All subfamily members possess two characteristic domains, an N-terminal C3HC4-type RING-HC finger and a C-terminal tumor necrosis factor (TNF) receptor associated factor (TRAF)-like substrate-binding domain (SBD).

second RING finger, HC subclass, found in mind bomb 2 (MIB2) and similar proteins; MIB2, also known as novel zinc finger protein (Novelzin), putative NF-kappa-B-activating protein 002N, skeletrophin, or zinc finger ZZ type with ankyrin repeat domain protein 1, is a large, multi-domain E3 ubiquitin-protein ligase that promotes ubiquitination of the cytoplasmic tails of Notch ligands. Especially, it promotes Delta ubiquitylation and endocytosis in Notch activation. Overexpression of MIB2, activates NF-kappaB and interferon-stimulated response element (ISRE) reporter activity. Moreover, MIB2 acts as a novel component of the activated B-cell CLL/lymphoma 10 (BCL10) complex and controls BCL10-dependent NF-kappaB activation. It also functions as a founder myoblast-specific protein that regulates myoblast fusion and muscle stability. MIB2 contains an MZM region with two Mib-Herc2 domains flanking a ZZ zinc finger, a REP region including two tandem Mib repeats, an ANK region that spans ankyrin repeats, and a RNG region consisting of two C3HC4-type RING-HC fingers.
