Anti-Sororin antibodies enable researchers to detect and measure the Sororin antigen in biological samples. This target is a reported synonym of the CDCA5 gene, which encodes cell division cycle associated 5. This protein is known to function in the cell cycle, among other biological roles. The human version of Sororin has a canonical amino acid length of 252 residues and a protein mass of 27.6 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Sororin is a member of the Sororin protein family.
