TP53RK

TP53-regulating kinase, also known as PRPK is an enzyme that in humans is encoded by the TP53RK gene. This protein is a serine/threonine protein kinase that phosphorylates p53 at Ser15.

PRPK is part of the KEOPS/EKC complex, which participates in transcription control, telomere regulation and tRNA modification.
