Anti-Kip2 antibodies enable researchers to detect and measure the Kip2 antigen in biological samples. This target is a reported synonym of the CIB2 gene, which encodes calcium and integrin binding family member 2. This protein is known to function in the regulation of intracellular calcium, among other biological roles. The human version of Kip2 has a canonical amino acid length of 187 residues and a protein mass of 21.6 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane and cytoplasm of cells and notably expressed in many tissues, such as the fallopian tube and nasopharynx.
