PPP1R15A (Protein Phosphatase 1 Regulatory Subunit 15A) is a Protein Coding gene. Diseases associated with PPP1R15A include Malignant Pleural Mesothelioma. Among its related pathways are Transcriptional activity of SMAD2/SMAD3-SMAD4 heterotrimer and Activation of cAMP-Dependent PKA. GO annotations related to this gene include protein kinase binding.This gene is a member of a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. The induction of this gene by ionizing radiation occurs in certain cell lines regardless of p53 status, and its protein response is correlated with apoptosis following ionizing radiation.
