Background: Radioresistance is a critical factor restricting efficacy of radiotherapy. Results: Phosphorylation of both rpS3 and TRAF2 induces dissociation of rpS3-TRAF2 complex and influences radioresistance through activation of NF-κB pathway. Conclusion: Phosphorylation of rpS3 and TRAF2 is a key control point of radioresistance in NSCLC cells. Significant: Our findings reveal a novel radioresistance mechanism through functional orchestration of rpS3, TRAF2, and NF-κB in NSCLC cells.
