Anti-FEZ1 antibodies are used in the immunodetection of the protein fasciculation and elongation protein zeta 1. In humans, the canonical protein has a reported length of 392 amino acid residues and a mass of 45.1 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be mainly expressed in the brain. A member of the Zygin protein family, FEZ1 is suspected to be involved in axonal outgrowth as component of the network of molecules that regulate cellular morphology and axon guidance machinery. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include zygin I, zygin-1, and UNC-76. FEZ1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some FEZ1 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.
