Anti-Choline kinase alpha antibodies are used for the immunodetection of the protein encoded by the CHKA gene. In humans, the canonical protein has a reported length of 457 amino acid residues and a mass of 52.2 kDa. Its subcellular localization is in the cytoplasm. 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 play an important role in phospholipid biosynthesis by catalyzing the phosphorylation of free choline to phosphocholine, the first step in phosphatidylcholine biosynthesis. Post-translational modifications have been described, including acetylation and phosphorylation. Other names for this target antigen include CHK and CK. Gene orthologs have been identified in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. A number of Choline kinase alpha antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
