Anti-CTXN antibodies enable researchers to detect and measure the CTXN antigen in biological samples. This target is a reported synonym of the CTXN1 gene, which encodes cortexin 1. This protein is believed to mediate extracellular or intracellular signaling of cortical neurons during forebrain development. The human version of CTXN has a canonical amino acid length of 82 residues and a protein mass of 9 kilodaltons. It is reported to be localized in the membrane of cells. CTXN is a member of the Cortexin protein family.
