Choline kinase alpha (CHKA)

Target
CHKA
Molecular classification
Enzyme
01

Overview

Choline kinase alpha (CHKA) is a cytosolic enzyme that catalyzes the phosphorylation of free choline to phosphocholine, the first and rate-limiting step in the CDP-choline pathway for phosphatidylcholine production. It plays an essential role in membrane biogenesis, lipid metabolism, signal transduction, and the regulation of cell growth and proliferation. CHKA is overexpressed in various cancers and is a target for small-molecule inhibitors under investigation as anticancer agents. It is also implicated in neurodevelopmental disorders.
