Anti-ethanolamine kinase antibodies enable researchers to detect and measure the ethanolamine kinase antigen in biological samples. This target is a reported synonym of the CHKA gene, which encodes choline kinase alpha. This protein is known to function in carbohydrate metabolism and homeostasis and the metabolism of lipids, among other biological roles. The human version of ethanolamine kinase has a canonical amino acid length of 457 residues and a protein mass of 52.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the bronchus and cervix. ethanolamine kinase is a member of the Choline/ethanolamine kinase protein family.
