Resumen
[ES] El diseño de fármacos por modelización molecular es un campo que va ganando importancia en los últimos años, no sólo por la cantidad creciente de literatura publicada, sino por el aumento de la potencia y la exactitud de los métodos. El objetivo de este estudio es demostrar la importancia de cierto dominio de BCL6 en la actividad biológica de esta proteína, utilizando la suite de programas de simulación molecular Amber12. Está demostrado que la sobreexpresión de BCL6 tiene significación clínica en varios tipos de linfoma: BCL6 interviene reprimiendo la transcripción de genes que se traducen en células B. El blanco del estudio es el dominio estructural BTB, situado en el extremo N-terminal de BCL6, en su forma complejada con el correpresor SMRT. La identificación de las interacciones más fuertes y estables entre proteína y correpresor es el primer paso para el desarrollo de fármacos contra el cáncer efectivos y específicos.

The purpose of this study is to prove the importance of a certain domain of BCL6 in the biological activity of this protein, using the Amber12 suite of molecular simulation programs. It has been proven that overexpression of BCL6 has clinical significance in several types of lymphoma: BCL6 participates suppressing transcription of genes that translate into B cells. The target of the study is BTB structural domain, placed at N-terminal end of BCL6, in its form complexed with corepressor SMRT. Identification of the strongest and most stable interactions between protein and corepressor is the first step to develop effective and specific drugs against cancer.
