Function
Plays a key role in phospholipid biosynthesis by catalyzing the phosphorylation of free choline to phosphocholine, the first step in phosphatidylcholine biosynthesis . Also phosphorylates ethanolamine, thereby contributing to phosphatidylethanolamine biosynthesis . Has higher activity with choline . May contribute to tumor cell growth . ; [Isoform 1]: This isoform plays a key role in lipolysis of lipid droplets following glucose deprivation . In response to glucose deprivation, phosphorylated by AMPK, promoting localization to lipid droplets . Phosphorylation is followed by acetylation by KAT5, leading to dissociation of the homodimer into a monomer . Monomeric CHKA isoform 1 is converted into a tyrosine-protein kinase, which phosphorylates lipid droplet structural proteins PLIN2 and PLIN3, leading to lipolysis of lipid droplets .
