Anti-CDKAL1 antibodies are used in the immunodetection of the protein CDK5 regulatory subunit associated protein 1 like 1. In humans, the canonical protein has a reported length of 579 amino acid residues and a mass of 65.1 kDa. Its subcellular localization is in the ER. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in pancreatic islets. A member of the Methylthiotransferase protein family, CDKAL1 is known to catalyze the methylthiolation of N6-threonylcarbamoyladenosine (t(6)A), leading to the formation of 2-methylthio-N6-threonylcarbamoyladenosine (ms(2)t(6)A) at position 37 in tRNAs that read codons beginning with adenine. Synonyms for this target antigen include threonylcarbamoyladenosine tRNA methylthiotransferase and tRNA-t(6)A37 methylthiotransferase. CDKAL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CDKAL1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
