NSD3-NUT fusion oncoprotein in NUT midline carcinoma: implications for a novel oncogenic mechanism

The existence of a family of fusion oncogenes in squamous cell carcinoma is unprecedented, and should lead to key insights into aberrant differentiation in NMC and possibly other squamous cell carcinomas. The involvement of the NSD3 methyltransferase as a component of the NUT fusion protein oncogenic complex identifies a new potential therapeutic target.
