Estudio de la proteína HINT1: actividad SUMO proteasa, regulación de canales TRPs e implicación en el síndrome bipolar y la actividad motora

Abstract

La proteína HINT1 (histidine triad nucleotide-binding protein 1), muy conservada en la filogenia, pertenece a la familia HIT, que se caracteriza por poseer una triada de histidinas que, en varios de sus miembros, está implicada en una actividad hidrolasa aunque, en el caso concreto de la HINT1 se desconocen sus sustratos fisiológicos. A nivel clínico, esta proteína se ha asociado con diversas patologías, particularmente con trastornos psiquiátricos, como la esquizofrenia y el trastorno bipolar, y motores, como la neuropatía axonal recesiva autosómica con neuromiotonía (ARAN-NM), en cuyos pacientes se han descrito 15 mutaciones puntuales recesivas de la HINT1 causantes de esta enfermedad. A nivel celular, la HINT1 se encuentra en membrana plasmática, núcleo y citosol. En la membrana plasmática, la HINT1 actúa como proteína de ensamblaje y/o chaperona interaccionando con una amplia variedad de proteínas de señalización, entre los que cabe destacar los reguladores de la señalización de las proteínas G (RGS) y los receptores de glutamato NMDA, además de ser esencial en la regulación funcional de varios receptores acoplados a proteínas G. En el núcleo, la HINT1 juega un papel importante como represor transcripcional asociándose con diferentes factores de transcripción, como el complejo Pontin/Reptin y el dominio intracelular (ICD) de la teneurina 1. Además, la HINT1 es una proteína supresora de tumores ya que participa en la respuesta al daño del ADN, promueve la apoptosis e inhibe la proliferación de células en diversos cánceres...
