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.

REFERENCIA DEL GRUPO Y/O INVESTIGADOR
Xavier Rovira se encuentra en su último año de tesis dentro del grupo de investigación del Dr. Jesús Giraldo. El Laboratorio de Farmacología de Sistemas y Bioinformática (Instituto de Neurociencias, Universidad Autónoma de Barcelona) es un equipo interdisciplinario compuesto por químicos, biólogos, informáticos y matemáticos. El grupo ha desarrollado nuevas metodologías combinando modelización matemática y molecular para el estudio de la interacción ligando-receptor y la transducción de señales

Dynamic acetylation of cytosolic phosphoenolpyruvate carboxykinase toggles enzyme activity between gluconeogenic and anaplerotic reactions

01-12-2018

Cytosolic phosphoenolpyruvate carboxykinase (PCK1) is considered a gluconeogenic enzyme; however, its metabolic functions and regulatory mechanisms beyond gluconeogenesis are poorly understood. Here, we describe that dynamic acetylation of PCK1 interconverts...
