DNA-PK Proteins

Protein Information

DNA-PK is a heterotrimeric, DNA-dependent protein kinase that initiates signaling cascades in response to DNA damage. DNA-PK is an atypical kinase, closely related to the PI3 kinases, and is often potently inhibited by small molecules designed to target PI3 kinases. DNA-PK encodes a component of the mediator complex, a transcriptional coactivator complex thought to be required for the expression of almost all genes. The mediator complex is recruited by transcriptional activators or nuclear receptors to induce gene expression, possibly by interacting with RNA polymerase II and promoting the formation of a transcriptional pre-initiation complex. Multiple transcript variants encoding different isoforms have been found for DNA-PK.
