Anti-FER antibodies are used in the immunodetection of the protein FER tyrosine kinase. In humans, the canonical protein has a reported length of 822 amino acid residues and a mass of 94.6 kDa. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Tyr protein kinase protein family, FER is reported to be a tyrosine-protein kinase that acts downstream of cell surface receptors for growth factors and plays a role in the regulation of the actin cytoskeleton, microtubule assembly, lamellipodia formation, cell adhesion, cell migration and chemotaxis. Synonyms for this target antigen include TYK3, p94-Fer, tyrosine-protein kinase Fer, feline encephalitis virus-related kinase FER, and PPP1R74. A number of FER antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
