Pontin and Reptin, two related ATPases with multiple roles in cancer

Studies in model organisms or cultured human cells suggest. potential implications in carcinogenesis for the AAA+ ATPases Pontin and Reptin. Both proteins are associated with several chromatin-remodeling complexes and have many functions including transcriptional regulation, DNA damage repair, and telomerase activity. They also interact with major oncogenic actors such as beta-catenin and c-myc and regulate their oncogenic function. We only now begin to get. insight into the role of Pontin and Reptin in human cancers.
