Anti-CLK1 antibodies are used in the immunodetection of the protein CDC like kinase 1. In humans, the canonical protein has a reported length of 484 amino acid residues and a mass of 57.3 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the caudate, urinary bladder, and appendix. A member of the CMGC Ser/Thr protein kinase protein family, CLK1 is known to be involved with peptidyl-serine phosphorylation and protein phosphorylation. Synonyms for this target antigen include CLK/STY, STY, dual specificity protein kinase CLK1, CDC28/CDC2-like kinase, protein tyrosine kinase STY, and CLK. CLK1 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some CLK1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
