Function

The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. Upon interaction with GNA12 promotes dephosphorylation of microtubule associated protein TAU/MAPT (PubMed:15525651). Required for proper chromosome segregation and for centromeric localization of SGO1 in mitosis (PubMed:16580887). Together with RACK1 adapter, mediates dephosphorylation of AKT1 at 'Ser-473', preventing AKT1 activation and AKT-mTOR signaling pathway (By similarity). Dephosphorylation of AKT1 is essential for regulatory T-cells (Treg) homeostasis and stability (By similarity). Part of the striatin-interacting phosphatase and kinase (STRIPAK) complexes. STRIPAK complexes have critical roles in protein (de)phosphorylation and are regulators of multiple signaling pathways including Hippo, MAPK, nuclear receptor and cytoskeleton remodeling. Different types of STRIPAK complexes are involved in a variety of biological processes such as cell growth, differentiation, apoptosis, metabolism and immune regulation (PubMed:18782753, PubMed:33633399). Regulates the recruitment of the SKA complex to kinetochores (PubMed:28982702).

Activity summary

The protein phosphatase 2 scaffold subunit A alpha isoform (PPP2R1A) functions as an important regulatory component of the serine/threonine phosphatase PP2A complex. Alternate names for PPP2R1A include PR65A and Aalpha. This protein has a mass of approximately 65 kDa and is widely expressed in many tissues including the brain heart and lungs. It serves as a scaffold for regulatory and catalytic subunits facilitating their assembly into the active enzyme complex.

Biological function summary

The PP2A complex plays a role in cell cycle control apoptosis and signal transduction. PPP2R1A forms a dimer with one catalytic and one regulatory subunit. This arrangement influences various cell signaling processes controlling cell growth and division. Through its position in the PP2A complex PPP2R1A moderates phosphorylation status of target proteins impacting diverse cellular activities.

Pathways

PPP2R1A participates in pathways like the Wnt signaling and the MAPK pathways acting as a brake on kinase-driven signaling. In the Wnt signaling pathway PP2A mediates beta-catenin degradation which influences gene expression related to cell growth. Within the MAPK pathway PPP2R1A interacts with kinases to modulate cellular responses to growth factors. Proteins such as AXIN1 in the Wnt signaling context are associated with the regulatory effects mediated by PPP2R1A.

Associated diseases and disorders

Alterations in PPP2R1A have been implicated in cancers like ovarian and uterine serous carcinoma. Mutations within this gene can disrupt PP2A activity leading to unchecked cell proliferation. Associations with beta-catenin highlight a significant role in tumorigenesis. In these contexts PPP2R1A's relationship with proteins such as beta-catenin and other components of the Wnt pathway indicates its importance in maintaining cellular homeostasis and its potential as a therapeutic target.
