Anti-SEPTIN14 antibodies are used in the immunodetection of the protein septin 14. In humans, the canonical protein has a reported length of 432 amino acid residues and a mass of 50 kDa. Its subcellular localization is in the cytoplasmic vesicles and cytoplasm. It is reported to have testis-specific expression. A member of the Septin GTPase protein family, SEPTIN14 is known to be involved with spermatid development. SEPTIN14 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species.
