Anti-CDKL1 antibodies are used in the immunodetection of the protein cyclin dependent kinase like 1. In humans, the canonical protein has a reported length of 358 amino acid residues and a mass of 41.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to be highly expressed in the kidney, and to a lower extent in ovary. A member of the CMGC Ser/Thr protein kinase protein family, CDKL1 is known to be involved with protein phosphorylation. Synonyms for this target antigen include P42, cyclin-dependent kinase-like 1 (CDC2-related kinase), protein kinase p42 KKIALRE, serine/threonine protein kinase KKIALRE, and KKIALRE. CDKL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CDKL1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
