Immunopharmacology Comments
Protein kinase, DNA-activated, catalytic polypeptide (DNA-PKcs) principally acts to repair DNA in a process called non-homologous end joining (NHEJ). NHEJ is required for V(D)J recombination (somatic recombination) in developing lymphocytes during the early stages of T and B cell maturation. DNA-PKcs knockout mice develop severe combined immunodeficiency as NHEJ is compromised and they are unable to construct the huge repertoire of antibodies and T cell receptors necessary for a fully developed adaptive immune response.
