Gene: CHKB (choline kinase beta) Homo sapiens
Symbol: CHKB
Name: choline kinase beta
Description: Exhibits choline kinase activity and ethanolamine kinase activity. Involved in phosphatidylethanolamine biosynthetic process. Predicted to localize to cytosol. Implicated in intellectual disability; megaconial type congenital muscular dystrophy; muscular dystrophy; narcolepsy; and recurrent hypersomnia.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: CHETK; CHKL; choline kinase-like protein; choline/ethanolamine kinase; choline/ethanolamine kinase beta; CK; CKB; CKEKB; EK; EKB; ethanolamine kinase beta; MDCMC
