PTPA (Protein Phosphatase 2 Phosphatase Activator) is a Protein Coding gene. Diseases associated with PTPA include Apical Myocardial Infarction and Leukemia, Acute Myeloid. Among its related pathways are DNA Damage and Regulation of CFTR activity (norm and CF). PTPA encodes a specific phosphotyrosyl phosphatase activator of the dimeric form of protein phosphatase 2A. Alternative splicing results in multiple transcript variants encoding different isoforms.
