PP2AP

PP2AP is a protein that plays a role in cellular processes. It is a regulatory subunit of protein phosphatase 2A (PP2A). PP2A is a serine/threonine phosphatase involved in a wide range of cellular functions, including cell cycle control, signal transduction, and apoptosis. PP2AP, also known as PR130, is one of several regulatory subunits that can associate with the catalytic and scaffolding subunits of PP2A. The specific subunit composition of PP2A can determine its substrate specificity and localization within the cell. PP2AP has been implicated in regulating PP2A activity towards specific substrates. Research suggests that PP2AP may influence the phosphatase's role in processes such as insulin signaling and cell migration. The precise mechanisms by which PP2AP modulates PP2A activity and its full spectrum of cellular functions are areas of ongoing investigation. Its interaction with other cellular components and its contribution to the overall regulation of PP2A's diverse roles are subjects of continued study in molecular and cell biology.
