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.

By similarity

This isoform plays a key role in lipolysis of lipid droplets following glucose deprivation (By similarity).

In response to glucose deprivation, phosphorylated by AMPK, promoting localization to lipid droplets (By similarity).

Phosphorylation is followed by acetylation by KAT5, leading to dissociation of the homodimer into a monomer (By similarity).

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 (By similarity).
