cd16471: RING-H2_RNF32 
RING finger, H2 subclass, found in RING finger protein 32 (RNF32) and similar proteins
RNF32 is mainly expressed in testis spermatogenesis, most likely in spermatocytes and/or in spermatids, suggesting a possible role in sperm formation. RNF32 contains two C3H2C3-type RING-H2 fingers separated by an IQ domain of unknown function. Although the biological function of RNF32 remains unclear, proteins with double RING-H2 fingers may act as scaffolds for binding several proteins that function in the same pathway.

Zn binding site
Feature 1: Zn binding site [ion binding site], 8 residue positions
Conserved feature residue pattern:C C C H H C C CClick to see conserved feature residue pattern help
Evidence:
  • Comment:based on the structures of other RING-H2 fingers with bound zinc
  • Comment:C3H2C3-type RING-H2 finger consensus motif: C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-H-X2-C-X(4-48)-C-X2-C, where X is any amino acid and the number of X residues varies in different fingers
  • Comment:A RING finger typically binds two zinc atoms, with its Cys and/or His side chains in a unique "cross-brace" arrangement.
