Anti-SEC11A antibodies are used in the immunodetection of the protein SEC11 homolog A, signal peptidase complex subunit. In humans, the canonical protein has a reported length of 179 amino acid residues and a mass of 20.6 kDa. Its subcellular localization is in the ER. Up to 4 different isoforms have been reported for this protein. A member of the Peptidase S26B protein family, SEC11A is reported to be a catalytic component of the signal peptidase complex (SPC) which catalyzes the cleavage of N-terminal signal sequences from nascent proteins as they are translocated into the lumen of the endoplasmic reticulum. Synonyms for this target antigen include SEC11L1, SPC18, SPCS4A, sid2895, signal peptidase complex catalytic subunit SEC11A, and 1810012E07Rik. SEC11A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SEC11A antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
