External Ids for DGKI Gene
This gene is a member of the type IV diacylglycerol kinase subfamily. Diacylglycerol kinases regulate the intracellular concentration of diacylglycerol through its phosphorylation, producing phosphatidic acid. The specific role of the enzyme encoded by this gene is undetermined, however, it may play a crucial role in the production of phosphatidic acid in the retina or in recessive forms of retinal degeneration.

GeneCards Summary for DGKI Gene
DGKI (Diacylglycerol Kinase, Iota) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include NAD+ kinase activity and GTPase inhibitor activity. An important paralog of this gene is DGKH.
Diacylglycerol kinases (DGKs) are a group of ten enzymes (DGKalpha, DGKbeta, DGKgamma, DGKdelta, DGKepsilon, DGKzeta, DGKeta, DGKtheta, DGKiota and DGKkappa) that metabolize 1,2,diacylglycerol (DAG) to produce phosphatidic acid (PA). They all contain a conserved C-terminal catalytic domain, two cysteine-rich Zn2+-finger motifs that bind DAG and an ATP-binding site, whilst the regulatory domain varies. DGKs are widely distributed throughout mammalian tissues and different isozymes have different subcellular localizations; some are cytosolic (for example DGKalpha), some are membrane-bound (for example DGKgamma is associated with the Golgi membrane) and some are nuclear (for example DGKzeta. DGKs have diverse biological roles as they participate in signal transduction by modulating levels of DAG in a variety of cellular responses to extracellular stimuli.
