Ppp1r15a Gene Summary [Mouse]
Enables protein phosphatase binding activity and protein phosphatase regulator activity. Involved in positive regulation of signal transduction by p53 class mediator; regulation of gene expression; and response to endoplasmic reticulum stress. Acts upstream of or within endoplasmic reticulum unfolded protein response. Predicted to be located in Golgi apparatus; membrane; and mitochondrion. Predicted to be part of protein phosphatase type 1 complex. Predicted to be active in endoplasmic reticulum. Is expressed in several structures, including central nervous system; genitourinary system; gut; heart; and hemolymphoid system gland. Used to study thalassemia. Orthologous to human PPP1R15A (protein phosphatase 1 regulatory subunit 15A). [provided by Alliance of Genome Resources, Jul 2025]
