RT Journal Article T1 A chemical approach for the synthesis of the DNA-binding domain of the oncoprotein MYC A1 Calo Lapido, Renata A1 Penas Tallón, Cristina A1 Jiménez Balsa, Adrián A1 Vázquez Sentís, Marco Eugenio A1 Mascareñas Cid, José Luis AB We describe the first chemical synthesis of a functional mutant of the DNA binding domain of the oncoprotein MYC, using two alternative strategies which involve either one or two Native Chemical Ligations (NCLs). Both routes allowed the efficient synthesis of a miniprotein which is capable of heterodimerizing with MAX, and replicate the DNA binding of the native protein. The versatility of the reported synthetic approach enabled the straightforward preparation of MYC and Omomyc analogues, as well as fluorescently labeled derivatives PB Royal Society of Chemistry YR 2019 FD 2019 LK http://hdl.handle.net/10347/20792 UL http://hdl.handle.net/10347/20792 LA eng NO Calo-Lapido, R., Penas, C., Jiménez-Balsa, A., Vázquez, M.
