Anti-OC120 antibodies enable researchers to detect and measure the OC120 antigen in biological samples. This target is a reported synonym of the PLEKHO1 gene, which encodes pleckstrin homology domain containing O1. This protein is known to function in the regulation of cell shape, among other biological roles. The human version of OC120 has a canonical amino acid length of 409 residues and a protein mass of 46.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, and cytoplasm of cells. Other names for this target antigen include CKIP-1, CKIP1, and JBP.
