Los sistemas tiorredoxina y el genoma humano

Abstract

Las tiorredoxinas y tiorredoxina reductasas fueron descubiertas en 1964 en E.coli como el sistema donador de electrones para la ribonucleótido reductasa, enzima fundamental que convierte ribonucleótidos en deoxirribonucleótidos (44, 59). Más tarde, el mismo sistema fue identificado en levaduras (31) y luego en prácticamente todos los organismos estudiados, incluyendo las plantas, que contienen sistemas de tiorredoxina adicionales involucrados en la transducción de energía luminosa (8), Sin embargo, hicieron falta casi 25 años para identificar el ortólogo humano de la tiorredoxina (107), que resultó ser un factor responsable de la inducción del receptor de interleukina 2 en células leucémicas adultas (100). Poco después, se identificó una segunda tiorredoxina en levaduras (61), surgiendo así el concepto de una familia de proteínas con función de tiorredoxina. Desde entonces, y fundamentalmente debido al advenimiento de los proyectos de secuenciación de genomas, el número de miembros de la familia de tiorredoxinas ha aumentado en todas las clases de organismos, desde las bacterias a los mamíferos.
