Domain Architecture (Details)
InterPro domains unassigned to SynO:
Quality control of intracellular proteins is essential for cellular homeostasis. Molecular chaperones recognise and contribute to the refolding of misfolded or unfolded proteins.hereas the ubiquitin-proteasome system mediates the degradation of such abnormal proteins. Ubiquitin-protein ligases (E3s) determine the substrate specificity for ubiquitylation and have been classified into HECT and RING-finger families. More recently.owever.-box proteins.hich contain a domain (the U box) of about 70 amino acids that is conserved from yeast to humans.ave been identified as a new type of E3 .The RING-finger is a specialised type of Zn-finger of 40 to 60 residues that binds two atoms of zinc.nd is probably involved in mediating protein-protein interactions. . There are two different variants.he C3HC4-type and a C3H2C3-type.hich is clearly related despite the different cysteine/histidine pattern. The latter type is sometimes referred to as RING-H2 finger. The RING domain is a protein interaction domain which has been implicated in a range of diverse biological processes.E3 ubiquitin-protein ligase activity is intrinsic to the RING domain ofc-Cbl and is likely to be a general function of this domain; Various RINGfingers exhibit binding to E2 ubiquitin-conjugating enzymes (Ubcs) .Several 3D-structures for RING-fingers are known . The 3D structure of the zinc ligation system is unique to the RING domain and is referred to as the cross-brace motif. The spacing of the cysteines in such a domain is C-x(2)-C-x(9 to 39)-C-x(1 to 3)-H-x(2 to 3)-C-x(2)-C-x(4 to 48)-C-x(2)-C. Metal ligand pairs one and three co-ordinate to bind one zinc ion.hilst pairs two and four bind the second.s illustrated in the following schematic representation:Note that in the older literature.ome RING-fingers are denoted as LIM-domains. The LIM-domain Zn-finger is a fundamentally different family.lbeit with similar Cys-spacing (see ).
  IPR001841:Zinc finger, RING-type
The NHL (NCL-1.T2A and LIN-41) repeat is found in a variety of enzymes of the copper type II.scorbate-dependent monooxygenase family which catalyse the C-terminus alpha-amidation of biological peptides . The repeat also occurs in a human zinc finger protein that specifically interacts with the activation domain of lentiviral Tat proteins . The repeat domain that is often associated with RING finger and B-box motifs .
