Resumen

Estudios recientes sugieren que un mismo tipo de receptor acoplado a proteína G puede activar diversas vías de señalización, siendo algunas de estas vías independientes de la activación de proteínas G. Además, ciertos ligandos han demostrado tener la capacidad de activar preferentemente una de estas vías. Esta característica, denominada selectividad funcional, puede ser clave para determinar el modo de acción de los fármacos. En el presente trabajo, se analiza este fenómeno en el contexto de la homodimerización de receptores utilizando como herramienta la modelización matemática.
