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.

variant of RING finger, HC subclass, found in interferon regulatory factor 2 (IRF2)-binding protein 2 (IRF-2BP2); IRF-2BP2, also known as IRF-2-binding protein 2 or DIF-1, is a nuclear protein that binds to the C-terminal repression domain of IRF-2 and acts as an IRF-2-dependent transcriptional corepressor, both enhancer-activated and basal transcription. IRF-2BP2 also specifically interacts with the C-terminal domain of the nuclear factor of activated T cells NFAT1 transcription factor, and negatively regulates the NFAT1-dependent transactivation of NFAT-responsive promoters. Moreover, IRF2BP2 suppresses the transactivation activity of p53 on both Bax and p21 promoters. It also shows anti-apoptotic activity through the modulation of the death domain in NRIF3. In addition, IRF2BP2 functions as a cofactor of VGLL4 and plays a critical role controlling gene expression in skeletal, cardiac, and smooth muscle cells. It is a muscle-enriched transcription factor required to activate vascular endothelial growth factor-A (VEGF-A) expression. IRF-2BP2 contains an N-terminal C4-type zinc finger and a C-terminal variant C3HC4-type RING-HC finger. The zinc finger is responsible for the homo- and hetero-dimerization between different members of the IRF-2BP2 family. The RING-HC finger interacts with IRF2 and also with nuclear receptor interacting factor 3 (NRIF3). Pssm-ID: 438376 Cd Length: 67 Bit Score: 130.98 E-value: 1.06e-36

This family corresponds to the HC subclass of RING (RING-HC) fingers that are characterized by containing C3HC4-type canonical RING-HC fingers or noncanonical RING-HC finger variants, including C4C4-, C3HC3D-, C2H2C4-, and C3HC5-type modified RING-HC fingers. The canonical RING-HC finger has been defined as C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-C-X2-C-X(4-48)-C-X2-C. It binds two Zn ions in a unique "cross-brace" arrangement, which distinguishes it from tandem zinc fingers and other similar motifs. RING-HC fingers can be found in a group of diverse proteins with a variety of cellular functions, including oncogenesis, development, viral replication, signal transduction, the cell cycle, and apoptosis.
