Anti-choline kinase beta antibodies are used for the immunodetection of the protein encoded by the CHKB gene. In humans, the canonical protein has a reported length of 395 amino acid residues and a mass of 45.3 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Choline/ethanolamine kinase protein family, it is known to have a key role in phospholipid metabolism, and catalyzes the first step of phosphatidylethanolamine and phosphatidylcholine biosynthesis. The gene encoding this protein is implicated in Muscular dystrophy. Other names for this target antigen include CHKL, CK, CKB, CKEKB, EK, EKB, MDCMC, and CHETK. Gene orthologs have been identified in the mouse, rat, bovine, frog and chimpanzee species. Some choline kinase beta antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
