Catalytic ActivityATP + 1,2-diacyl-sn-glycerol = ADP + 1,2- diacyl-sn-glycerol 3-phosphate.
FunctionDisplays a strong preference for 1,2-diacylglycerols over 1,3-diacylglycerols, but lacks substrate specificity among molecular species of long chain diacylglycerols. Isoform 2 but not isoform 1 regulates RASGRP1 activity.
InteractionP06400:RB1; NbExp=6; IntAct=EBI-715527, EBI-491274; P28749:RBL1; NbExp=2; IntAct=EBI-715527, EBI-971402; Q08999:RBL2; NbExp=2; IntAct=EBI-715527, EBI-971439;
PtmPhosphorylation of the MARCKS homology domain by PKC reduces nuclear accumulation of DGK-zeta.
Sequence CautionSequence=AAB60859.1; Type=Frameshift; Positions=166, 167; Evidence= ;
SimilarityBelongs to the eukaryotic diacylglycerol kinase family.
SimilarityContains 1 DAGKc domain. {ECO
SimilarityContains 2 ANK repeats. {ECO
SimilarityContains 2 phorbol-ester/DAG-type zinc fingers.
Subcellular LocationCytoplasm. Nucleus. Cell membrane.
SubunitInteracts with the PDZ domain of the syntrophin SNTG1 and that of SNX27. Isoform 2 forms a signaling complex with RASGRP1 and HRAS. {ECO
Tissue SpecificityHighest levels in brain, and substantial levels in skeletal muscle, heart, and pancreas. Isoform 1 is predominantly expressed in muscle.
