Anti-Septin 4 antibodies are used for the immunodetection of the protein encoded by the SEPTIN4 gene. In humans, the canonical protein has a reported length of 478 amino acid residues and a mass of 55.1 kDa. Its subcellular localization is in the cytoplasmic vesicles and cytoplasm. Alternative splicing is reported to yield 8 different isoforms for this protein. It is found to be widely expressed in adult and fetal tissues with highest expression in adult brain, heart, liver and adrenal gland and fetal heart, kidney, liver and lung. A member of the Septin GTPase protein family, it is known to be involved with the apoptotic pathway. Other names for this target antigen include BRADEION, C17orf47, CE5B3, H5, MART, PNUTL2, hCDCREL-2, and ARTS. Gene orthologs have been identified in the mouse, rat, bovine, frog and chimpanzee species. A number of Septin 4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
