cd20801: C1_DGKepsilon_typeIII_rpt1 
first protein kinase C conserved region 1 (C1 domain) found in type III diacylglycerol kinase, DAG kinase epsilon, and similar proteins
Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. DAG kinase epsilon, also called diglyceride kinase epsilon (DGK-epsilon), is the only isoform classified as type III; it possesses a hydrophobic domain in addition to C1 and catalytic domains that are present in all DGKs, and shows selectivity for acyl chains. It is highly selective for arachidonate-containing species of DAG. It may terminate signals transmitted through arachidonoyl-DAG or may contribute to the synthesis of phospholipids with defined fatty acid composition. DAG kinase epsilon contains two copies of the C1 domain. 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 Homo sapiens DGKdelta binds two Zn2+ ions
