Background

Parafibromin, the product of gene HPRT2, acts as a tumor suppressor protein by inhibiting cell proliferation and blocking expression of cyclin D1 when overexpressed. Parafibromin has also been shown to bind with the PAF1 complex / RNA polymerase II which is involved with transcription elongation and the RNA processing pathway.
