cd20829: C1_PIK3R-like_rpt1 
first protein kinase C conserved region 1 (C1 domain) found in uncharacterized phosphatidylinositol 3-kinase regulatory subunit-like proteins
The family includes a group of uncharacterized proteins that show high sequence similarity to vertebrate phosphatidylinositol 3-kinase regulatory subunits (PIK3Rs), which bind to activated (phosphorylated) protein-tyrosine kinases through its SH2 domain and regulate their kinase activity. Unlike typical PIK3Rs, members of this family have two C1 domains. This model corresponds to the first one. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

Zn binding site
Feature 1:Zn binding site [ion binding site]
Evidence:
  • Comment:Two non-consecutive sets of zinc-binding residues form two separate metal-binding sites.
  • Comment:Based on the structure evidence that Rattus norvegicus ROCK2 binds two Zn2+ ions
