PRKDC (DNA-dependent protein kinase catalytic subunit) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a drug target, a biomarker and a DNA repair gene, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Melanoma, Non-small-cell lung cancer and Diffuse large B-cell lymphoma.
Serine/threonine-protein kinase that acts as a molecular sensor for DNA damage. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination. Must be bound to DNA to express its catalytic properties.
CIViC holds 3 clinical evidence items and 0 assertions across 1 variant, naming Anti-CTLA-4 Monoclonal Antibody and Anti-PD1 Monoclonal Antibody.

No product in this corpus aims at PRKDC yet. Kinases are switched on by binding ATP inside the cell, so most drugs are small molecules shaped to plug that ATP pocket.
Broadly expressed or essential: HPA lists PRKDC among essential proteins and finds the RNA at low tissue specificity; a medicine acting on the wild-type protein would expose normal tissue too. HPA PRKDC: RNA low tissue specificity; high antibody staining in 43 normal tissues; highest cancer staining breast cancer (12 of 12 high). Distribution: 3 cancer families in the corpus carry a prevalence row, label threshold or catalogue link for it (Skin cancer (all types), Lung cancer (all types), Lymphoma); Open Targets associates it with 0 specific cancer types at or above 0.5. (Rule 7 of scripts/fetch-target-specificity.ts.)

Serine/threonine-protein kinase that acts as a molecular sensor for DNA damage. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination. Must be bound to DNA to express its catalytic properties. Promotes processing of hairpin DNA structures in V(D)J recombination by activation of the hairpin endonuclease artemis (DCLRE1C). Recruited by XRCC5 and XRCC6 to DNA ends and is required to (1) protect and align broken ends of DNA, thereby preventing their degradation, (2) and sequester the DSB for repair by NHEJ. Acts as a scaffold protein to aid the localisation of DNA repair proteins to the site of damage. Location: Nucleus; Nucleus, nucleolus; Cytoplasm, cytosol (UniProt). Locus 8q11.21 (HGNC).
RNA: low tissue specificity, detected in all normal tissues.
Medium: Liver, Smooth muscle.
