Anti-centrosomal protein 44kDa antibodies enable researchers to detect and measure the centrosomal protein 44kDa antigen in biological samples. This target is a reported synonym of the CEP44 gene, which encodes centrosomal protein 44. The human version of centrosomal protein 44kDa has a canonical amino acid length of 390 residues and a protein mass of 44.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include centrosomal protein of 44 kDa, HBV PreS1-transactivated protein 3, and centrosomal protein 44kDa.
