Anti-PCDHX antibodies enable researchers to detect and measure the PCDHX antigen in biological samples. This target is a reported synonym of the PCDH11X gene, which encodes protocadherin 11 X-linked. This protein is known to function in cell adhesion, among other biological roles. The human version of PCDHX has a canonical amino acid length of 1347 residues and a protein mass of 147.6 kilodaltons, although 8 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the rectum, ovary, colon, cerebral cortex, and bone marrow.
