The R2TP complex which comprises of RUVBL1, RUVBL2, PIH1D1 and RPAP3 in humans is known to be a specialized Co-chaperone of Hsp-90 protein. This multimeric-protein complex is involved in the assembly and maturation of several multi-subunit complexes including RNA polymerase II, small nucleolar ribonucleoproteins, and complexes containing phosphatidylinositol-3-kinase-like kinases. Since their discovery as a co-chaperone of Hsp90, the R2TP complex is involved in multitude of cellular processes including, chromatin remodelling, transcription regulation, ribonucleoprotein complex biogenesis, mitotic assembly, telomerase complex assembly, and apoptosis. Lymphoma arises from the abnormal proliferation of B-cells and the R2TP complex have been reported to play an important role in the activation of p53 and RB. Therefore, the inactivation in any of the tumor suppressor pathways can drive cells to malignancy.However, there are multiple factors which may contribute towards malignancy but the folding defects in these tumor suppressor pathways could be one of the reasons. R2TP is tightly linked with oncogenesis and its inhibition can decrease the proliferation activity of cancer cells. So, the multisubunit chaperone complex as well as its components could be promising candidates for cancer chemotherapy.
