Enables protein phosphatase binding activity and protein phosphatase regulator activity. Involved in regulation of macromolecule metabolic process 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).
