Anti-diacylglycerol kinase, iota antibodies enable researchers to detect and measure the diacylglycerol kinase, iota antigen in biological samples. This target is a reported synonym of the DGKI gene, which encodes diacylglycerol kinase iota. This protein is known to function in intracellular signal transduction, among other biological roles. The human version of diacylglycerol kinase, iota has a canonical amino acid length of 1065 residues and a protein mass of 117 kilodaltons. It is reported to be localized in the cell membrane, nucleus, cell projections, and cytoplasm of cells. diacylglycerol kinase, iota is a member of the Eukaryotic diacylglycerol kinase protein family.
