Summary
Enables choline kinase activity. Predicted to be involved in CDP-choline pathway and phosphatidylethanolamine biosynthetic process. Predicted to act upstream of or within muscle organ development and phosphatidylcholine biosynthetic process. Predicted to be active in cytoplasm. 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, Nov 2024]
Expression
Biased expression in Heart (RPKM 120.4), Thymus (RPKM 109.6) and 9 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
