RESUMEN
Proteostasis es el término que se ha ocupado para definir a la homeostasis proteínica dentro de la célula. Este concepto abarca el estudio de las proteínas de manera individual, desde su síntesis, ubicación celular y función, hasta su vida media y degradación. Sin embargo, la proteostasis también se enfoca en la actividad grupal de las proteínas, analizando cuales de ellas funcionan dentro de una red de trabajo. Cuando las proteínas interactúan como una red de trabajo, producen flujos de información a través de diversos componentes. La eficiente coordinación entre las proteínas que conforman el flujo de la información es esencial para el correcto funcionamiento y supervivencia de la célula.
