Anti-SPATA31E1 antibodies are used in the immunodetection of the protein SPATA31 subfamily E member 1. In humans, the canonical protein has a reported length of 1445 amino acid residues and a mass of 157.1 kDa. Its subcellular localization is in the membrane. It is notably expressed in the testis. A member of the SPATA31 protein family, SPATA31E1 is believed to play a role in spermatogenesis. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include FAM75-like protein C9orf79, XXyac-YM21GA2.5, family with sequence similarity 75, member E1, protein FAM75E1, and spermatogenesis-associated protein 31E1. SPATA31E1 gene orthologs have been reported in the mouse, rat and chimpanzee species. Immunofluorescence is the most common application for the SPATA31E1 antibodies listed below. Immunocytochemistry and Immunohistochemistry are also common applications.
