The function of Ensembl gene identifier ENSG00000274588 (DGKK, diacylglycerol kinase kappa) is as follows. Diacylglycerol kinase that converts diacylglycerol/DAG into phosphatidic acid/phosphatidate/PA and regulates the respective levels of these two bioactive lipids (PubMed:16210324, PubMed:23949095). Thereby, acts as a central switch between the signaling pathways activated by these second messengers with different cellular targets and opposite effects in numerous biological processes (Probable). {ECO:0000269|PubMed:16210324, ECO:0000269|PubMed:23949095, ECO:0000305}.
