Protein attributes

Sequence length	567 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Highly selective for arachidonate-containing species of diacylglycerol (DAG). May terminate signals transmitted through arachidonoyl-DAG or may contribute to the synthesis of phospholipids with defined fatty acid composition.
Catalytic activity	ATP + 1,2-diacylglycerol = ADP + 1,2-diacyl-sn-glycerol 3-phosphate.
Subcellular location	Membrane; Multi-pass membrane protein Potential.
Tissue specificity	Expressed predominantly in testis.
Sequence similarities	Belongs to the eukaryotic diacylglycerol kinase family. Contains 1 DAGKc domain. Contains 2 phorbol-ester/DAG-type zinc fingers.
