Disruption of R2TP-mediated PIKK maturation with de novo designed binders
Phosphatidylinositol 3-kinase-related kinases (PIKKs), including ATM, ATR, DNA-PKcs, SMG1, TRRAP and mTOR, are regulators of gene expression, DNA damage response and metabolism. Their maturation depends on R2TP, a co-chaperone complex comprising the RUVBL1/2 AAA+ ATPase, RPAP3 and PIH1D1. While small-molecule RUVBL1/2 inhibitors have shown promise in cancer models, the presence of RUVBL1/2 in…
