Anti-KSR2 antibodies are used in the immunodetection of the protein kinase suppressor of ras 2. In humans, the canonical protein has a reported length of 950 amino acid residues and a mass of 107.6 kDa. Its subcellular localization is in the membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be mainly expressed in the brain and kidney. A member of the TKL Ser/Thr protein kinase protein family, KSR2 is known to be involved with protein phosphorylation. Post-translational modifications have been described, including phosphorylation. KSR2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of KSR2 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.
