Summary: Enables ATP binding activity; choline binding activity; and phosphotransferase activity, alcohol group as acceptor. Involved in several processes, including choline metabolic process; ethanolamine metabolic process; and response to 3-methylcholanthrene. Predicted to be located in lipid droplet. Predicted to be active in cytosol. Biomarker of colon cancer and transient cerebral ischemia. Orthologous to human CHKA (choline kinase alpha). [provided by Alliance of Genome Resources, Dec 2024]

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.
