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 (PubMed:17055435, 18394995, 30595372). 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 (PubMed:18394995, 30595372). Interacts with NXN; the interaction is direct (By similarity). Interacts with KCTD20 (By similarity). Interacts with BTBD10 (By similarity). Interacts with SGO1 and SGO2 (PubMed:16580887, 16541025, 17485487). Interacts with TP53 (PubMed:17245430). Interacts with AXIN1; the interaction dephosphorylates AXIN1 (PubMed:9920888). Interacts with PIM3; this interaction promotes dephosphorylation, ubiquitination and proteasomal degradation of PIM3 (PubMed:12473674). Interacts with RAF1 (PubMed:10801873). Interaction with IGBP1 protects unassembled PPP2CA from degradative ubiquitination (PubMed:9647778, 19818709, 20092282). Interacts with GSK3B (via C2 domain) (PubMed:20080667). Interacts with MFHAS1; retains PPP2CA into the cytoplasm and excludes it from the nucleus (PubMed:28609714). Interacts with PABIR1/FAM122A (PubMed:27588481). Interacts with ADCY8; interaction is phosphatase activity-dependent; antagonizes interaction between ADCY8 and calmodulin (PubMed:16258073). Interacts with CRTC3 (when phosphorylated at 'Ser-391') (PubMed:30611118). Interacts with SPRY2; the interaction is inhibited by TESK1 interaction with SPRY2, possibly by vesicular sequestration of SPRY2 (PubMed:17974561). Interacts with TRAF3IP3 (PubMed:30115741). Interacts with AMBRA1 (via PxP motifs); enhancing interaction between PPP2CA and MYC or FOXO3 (PubMed:25438055, 30513302). Forms a complex with AMBRA1 and BECN1; AMBRA1 and BECN1 components of the complex regulate MYC stability via different pathways (PubMed:25803737).
