Anti-FRA antibodies enable researchers to detect and measure the FRA antigen in biological samples. This target is a reported synonym of the FOSL1 gene, which encodes FOS like 1, AP-1 transcription factor subunit. This protein is known to function in chemotaxis and in utero embryonic development, among other biological roles. The human version of FRA has a canonical amino acid length of 271 residues and a protein mass of 29.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and notably expressed in the tonsil, stomach, small intestine, rectum, and kidney. FRA is a member of the BZIP protein family. Indicated applications for FRA antibodies listed below include ELISA, Western Blot, Immunofluorescence, Immunoprecipitation, and Immunohistochemistry.
