The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Zinc/RING finger domain, C3HC4 (zinc finger)
".
FunFam 2037: ERAD-associated E3 ubiquitin-protein ligase hrd1
Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.
There are 4 GO terms relating to "molecular function"
The search results have been sorted with the annotations that are found most frequently at the top of the

Protein binding GO:0005515

Ubiquitin protein ligase activity GO:0061630
Catalysis of the transfer of ubiquitin to a substrate protein via the reaction X-ubiquitin + S -> X + S-ubiquitin, where X is either an E2 or E3 enzyme, the X-ubiquitin linkage is a thioester bond, and the S-ubiquitin linkage is an amide bond: an isopeptide bond between the C-terminal glycine of ubiquitin and the epsilon-amino group of lysine residues in the substrate or, in the linear extension of ubiquitin chains, a peptide bond the between the C-terminal glycine and N-terminal methionine of ubiquitin residues.

Negative regulation of transcription by transcription factor catabolism GO:0010620
Any process that stops, prevents, or reduces the frequency, rate or extent of DNA-dependent transcription using a mechanism that involves the catabolism of a sequence-specific DNA-binding transcription factor by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.

|
Ubiquitin-dependent ERAD pathway GO:0030433
The series of steps necessary to target endoplasmic reticulum (ER)-resident proteins for degradation by the cytoplasmic proteasome. Begins with recognition of the ER-resident protein, includes retrotranslocation (dislocation) of the protein from the ER to the cytosol, protein ubiquitination necessary for correct substrate transfer, transport of the protein to the proteasome, and ends with degradation of the protein by the cytoplasmic proteasome.

1 | O74757 (/IMP) |
|
Protein modification by small protein conjugation or removal GO:0070647
A protein modification process in which one or more groups of a small protein, such as ubiquitin or a ubiquitin-like protein, are covalently attached to or removed from a target protein.

Hrd1p ubiquitin ligase complex GO:0000836
A multiprotein complex that recognizes and ubiquitinates proteins with misfolded luminal and membrane domains during ER-associated protein degradation (ERAD). In S. cerevisiae, this complex contains the ubiquitin ligase Hrd1p. In mammals, this complex contains the ubiquitin ligase HRD1 (Synoviolin) or AMFR (gp78).

Cell cortex GO:0005938
