The <i>HRPT2</i> Tumor Suppressor Gene Product Parafibromin Associates with Human PAF1 and RNA Polymerase II

Abstract excerpt

Inactivation of the HRPT2 tumor suppressor gene is associated with the pathogenesis of the hereditary hyperparathyroidism-jaw tumor syndrome and malignancy in sporadic parathyroid tumors. The cellular function of the HPRT2 gene product, parafibromin, has not been defined yet. Here we show that parafibromin physically interacts with human orthologs of yeast Paf1 complex components, including PAF1, LEO1, and CTR9,...
