Enables choline kinase activity. Acts upstream of or within muscle organ development and phosphatidylcholine biosynthetic process. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; central nervous system; cranium; heart; and sensory organ. Used to
study megaconial type congenital muscular dystrophy. Human ortholog(s) of this gene implicated in intellectual disability; megaconial type congenital muscular dystrophy; muscular dystrophy; narcolepsy; and recurrent hypersomnia. Orthologous to human CHKB (choline kinase beta). [provided by Alliance of Genome Resources, Jul 2025]
This locus represents naturally occurring read-through transcription between the neighboring choline kinase beta (Chkb) and carnitine palmitoyltransferase 1b, muscle (Cpt1b) genes. Similar read-through transcription has also been identified between the homologou
s genes in human and rat. These read-through transcripts are candidates for nonsense-mediated mRNA decay (NMD) and are unlikely to produce a protein; the functional significance of these transcripts has yet to be determined. [provided by RefSeq, Nov 2010]
