Anti-CDK5R1 antibodies are used in the immunodetection of the protein cyclin dependent kinase 5 regulatory subunit 1. In humans, the canonical protein has a reported length of 307 amino acid residues and a mass of 34.1 kDa. Its subcellular localization is in the cell membrane. A member of the Cyclin-dependent kinase 5 activator protein family, CDK5R1 is known to be involved with axon guidance and brain development. Post-translational modifications have been described, including ubiquitination, protein cleavage, myristoylation and phosphorylation. Synonyms for this target antigen include CDK5R, NCK5A, p23, p25, p35, p35nck5a, cyclin-dependent kinase 5 activator 1, and CDK5P35. CDK5R1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 60 citations in the literature describe the use of CDK5R1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
