Anti-FSCB antibodies are used in the immunodetection of the protein fibrous sheath CABYR binding protein. In humans, the canonical protein has a reported length of 825 amino acid residues and a mass of 88 kDa. Its subcellular localization is in the cell projections. It is notably expressed in the testis. FSCB is suspected to be involved in the later stages of fibrous sheath biogenesis and spermatozoa capacitation. Post-translational modifications have been described, including phosphorylation. FSCB gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is the most common application for the FSCB antibodies listed below. ELISA and Immunohistochemistry are also common applications.
