DNA-Dependent Protein Kinase Catalytic Subunit, Recombinant, Dictyostelium Discoideum, aa3910-4250,

Serine/threonine-protein kinase that acts as a molecular sensor for DNA damage. Is recruited to DNA ends by the Ku70/Ku80 heterodimer and is involved in DNA non-homologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination. This activity is only apparent when DNA damage is administered in G1 phase of the cell cycle. Required for efficient signaling of DNA double-stranded breaks via phosphorylation of H2AX during G1. Source: Partial recombinant protein corresponding to aa3910-4250 of Dictyostelium Discoideum DNA-Dependent Protein Kinase Catalytic Subunit, fused to 10xHis-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E. coli.
