New Publication from Dr. Linda Penn
MBP scientist Dr. Linda Penn and has led a team of researchers, which includes MBP scientists Dr. David Andrews, Dr. Cheryl Arrowsmith and Dr. Brian Raught in the publication of a new Nature article entitled ‘MYC protein interactors in gene transcription and cancer.’
The transcription factor and oncoprotein MYC is a potent driver of many human cancers and can regulate numerous biological activities that contribute to tumorigenesis. How a single transcription factor can regulate such a diverse set of biological programmes is central to the understanding of MYC function in cancer. In this Perspective, we highlight how multiple proteins that interact with MYC enable MYC to regulate several central control points of gene transcription. These include promoter binding, epigenetic modifications, initiation, elongation and post-transcriptional processes. Evidence shows that a combination of multiple protein interactions enables MYC to function as a potent oncoprotein, working together in a ‘coalition model’, as presented here. Moreover, as MYC depends on its protein interactome for function, we discuss recent research that emphasizes an unprecedented opportunity to target protein interactors to directly impede MYC oncogenesis.
