Unconventional prefoldin RPB5 interactor is a protein that in humans is encoded by the C19orf2 gene.The protein encoded by this gene binds to RNA polymerase II subunit 5 (RPB5) and negatively modulates transcription through its binding to RPB5. The encoded protein seems to have inhibitory effects on various types of activated transcription but it requires the RPB5-binding region. This protein acts as a corepressor.
