Anti-t-complex 11 antibodies are used for the immunodetection of the protein encoded by the TCP11 gene. In humans, the canonical protein has a reported length of 503 amino acid residues and a mass of 56.1 kDa. Its subcellular localization is in the cytoplasmic vesicles and membrane. Alternative splicing is reported to yield 7 different isoforms for this protein. A member of the TCP11 protein family, it is reported to play a role in the process of sperm capacitation and acrosome reactions. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include FPPR, T-complex protein 11 homolog, fertilization-promoting peptide receptor, t-complex 11 (a murine tcp homolog), and D6S230E. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species. Some t-complex 11 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
