El inhibidor nuclear de la fosfatasa 1 (PPP1R8) es una enzima codificada en humanos por el gen PPP1R8.[1] [2] [3]

Este gen, por medio de splicing alternativo, codifica tres diferentes isoformas. Dos de ellas son inhibidores específicos de tipo 1 serina/treonina fosfatasa y pueden unir, pero no romper el [ARN]]. La tercera isoforma no posee la función inhibidora fosfatasa, pero es una endorribonucleasa de hebra sencilla semejante a la ARNasa E de Escherichia coli. Esta isoforma requiere magnesio para su función y rompe específicamente regiones del ARN ricas en A+U.[3]
