Anti-KALRN antibodies are used in the immunodetection of the protein kalirin RhoGEF kinase. In humans, the canonical protein has a reported length of 2986 amino acid residues and a mass of 340.3 kDa. Its subcellular localization is in the cytoplasm. Up to 5 different isoforms have been reported for this protein. It is notably expressed in the nasopharynx, fallopian tube, cerebral cortex, cerebellum, and bronchus. A member of the CAMK Ser/Thr protein kinase protein family, KALRN is reported to promote the exchange of GDP by GTP. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include ARHGEF24 and CHD5. KALRN gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some KALRN antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
