Anti-oxidative stress responsive kinase 1 antibodies are used for the immunodetection of the protein encoded by the OXSR1 gene. In humans, the canonical protein has a reported length of 527 amino acid residues and a mass of 58 kDa. Its subcellular localization is in the cytoplasm. It is widely expressed across many tissue types. A member of the STE Ser/Thr protein kinase protein family, it is known to be involved with intracellular signal transduction. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include serine/threonine-protein kinase OSR1, oxidative stress responsive 1, oxidative stress-responsive 1 protein, and OSR1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
