Anti-FHF complex subunit HOOK interacting protein 2A antibodies are used for the immunodetection of the protein encoded by the FHIP2A gene. In humans, the canonical protein has a reported length of 765 amino acid residues and a mass of 86.6 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the FHIP protein family, it is known to be required for proper functioning of the nervous system. Other names for this target antigen include family with sequence similarity 160 member B1 and protein FAM160B1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
