Anti-XAP-6 antibodies enable researchers to detect and measure the XAP-6 antigen in biological samples. This target is a reported synonym of the PLXNA3 gene, which encodes plexin A3. This protein is known to function in axon guidance and brain development, among other biological roles. The human version of XAP-6 has a canonical amino acid length of 1871 residues and a protein mass of 207.7 kilodaltons. It is reported to be localized in the cell membrane of cells. XAP-6 is a member of the Plexin protein family.
