Summary: Enables protein phosphatase binding activity and protein phosphatase regulator activity. Involved in positive regulation of peptidyl-serine phosphorylation; 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, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
