8.3 Factors affecting mobility: multivariate analyses

Las características de las proteínas MVIIA y EETI-II permiten la mutación de su secuencia de aminoácidos en una región que no interactúa con el resto de la miniproteína, sin modificar su estructura radicalmente. Las regiones de interacción identificadas de la ebvIL-10 con su receptor, contienen la longitud adecuada para ser introducidas en nuestras miniproteínas andamio. Con el diseño y modelado de las proteínas mutantes, se obtuvieron seis proteínas específicas para analizar médiate Docking. El refinamiento por dinámica molecular de las proteínas mutantes nos permitió conocer un aproximado de la estructura y el acomodo especial de los aminoácidos en cada una de ellas. El análisis de acoplamiento molecular realizado a cada una de las miniproteínas mutantes muestra a los diseños MVIIA_L1 y EETI_L1 como potenciales inhibidores de la ebvIL-10. El siguiente paso de este trabajo debería ser la validación in vitro e in vivo de los diseños realizados en este trabajo. La presente tesis permite concluir en base a los cálculos computacionales obtenidos que el método de diseño in silico de proteínas específicas es una opción viable para la creación de potenciales fármacos inhibidores de la ebvIL-10, minimizando el costo de diseño inicial, típicamente realizado mediante experimentación bioquímica.
