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).

PP2A consists of a common heterodimeric core enzyme, composed of PPP2CA a 36 kDa catalytic subunit (subunit C) and PPP2R1A a 65 kDa constant regulatory subunit (PR65 or subunit A), that associates with a variety of regulatory subunits. Proteins that associate with the core dimer include three families of regulatory subunits B (the R2/B/PR55/B55, R3/B''/PR72/PR130/PR59 and R5/B'/B56 families), the 48 kDa variable regulatory subunit, viral proteins, and cell signaling molecules.

Found in a complex with at least ARL2, PPP2CB, PPP2R1A, PPP2R2A, PPP2R5E and TBCD (By similarity).

Interacts with FOXO1; the interaction dephosphorylates FOXO1 on AKT-mediated phosphorylation sites (By similarity).

Interacts with IPO9 (PubMed:12670497).

Interacts with TP53 and SGO1 (PubMed:17245430, PubMed:16580887).

Interacts with PLA2G16; this interaction might decrease PP2A activity (PubMed:17374643).

Interacts with CTTNBP2NL (PubMed:18782753).

Interacts with GNA12; the interaction promotes protein phosphatase 2A activation causing dephosphorylation of MAPT (PubMed:15525651).

Interacts with CIP2A; this interaction stabilizes CIP2A (PubMed:28174209).

Interacts with PABIR1/FAM122A (PubMed:27588481).

Interacts with ADCY8; antagonizes interaction between ADCY8 and calmodulin (By similarity).

Interacts with CRTC3 (when phosphorylated at 'Ser-391') (PubMed:30611118).

Interacts with SPRY2 (PubMed:17974561).

<p>This subsection of the 'Family and domains' section provides general information on the biological role of a domain. The term 'domain' is intended here in its wide acceptation, it may be a structural domain, a transmembrane region or a functional domain. Several domains are described in this subsection.<p><a href='/help/domain_cc' target='_top'>More...</a></p>Domaini

Each HEAT repeat appears to consist of two alpha helices joined by a hydrophilic region, the intrarepeat loop. The repeat units may be arranged laterally to form a rod-like structure.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
