DGK

Diacylglycerol kinase;

DGK (Diacylglycerol Kinase) modulates the balance between DAG and phosphatidic acid (PA). DGK phorylates DAG to generate PA. DGK has ten mammalian DGK subtypes (α-κ) with subtype-specific tissue distribution, and they can be classified into 5 types. Among them, DGKα and DGKζ specifically regulate the pool of DAG that is generated as a second messenger after stimulation of the T cell receptor. Whereas, DGKζ is the dominant isoform in T cells. Dysregulation of certain DGK isoforms leads to DAG-activation of PKC, attenuation of insulin signaling, and dysregulation of glucose metabolism. DGK plays a role in many physiological events, including cell proliferation and migration, glucose intake, immunity and neuronal network construction[1][2][3].
