Function ： Plays a key role in phospholipid biosynthesis by catalyzing the phosphorylation of free choline to phosphocholine, the first step in phosphatidylcholine biosynthesis (PubMed:19915674, PubMed:34077757, PubMed:17007874). Also phosphorylates ethanolamine, thereby contributing to phosphatidylethanolamine biosynthesis (PubMed:19915674, PubMed:17007874). Has higher activity with choline (PubMed:19915674, PubMed:17007874). May contribute to tumor cell growth (PubMed:19915674).., [Isoform 1]: This isoform plays a key role in lipolysis of lipid droplets following glucose deprivation (PubMed:34077757). In response to glucose deprivation, phosphorylated by AMPK, promoting localization to lipid droplets (PubMed:34077757). Phosphorylation is followed by acetylation by KAT5, leading to dissociation of the homodimer into a monomer (PubMed:34077757). 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 (PubMed:34077757)..

Subcellular locationi ：Cytoplasm, cytosol.,[Isoform 1]: Lipid droplet.

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 1% w/v BSA, 1X TBST at 4°C overnight.
