Summary
PPP2R5B (protein phosphatase 2 regulatory subunit B’beta, HGNC:9310) is a protein-coding gene on chromosome 11q13.1, encoding Serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit beta isoform (Q15173). As the regulatory component of the serine/threonine-protein phosphatase 2A (PP2A) holoenzyme, modulates substrate specificity, subcellular localization, and responsiveness to phosphorylation.
The product of this gene belongs to the phosphatase 2A regulatory subunit B family. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes a beta isoform of the regulatory subunit B56 subfamily.

Function. As the regulatory component of the serine/threonine-protein phosphatase 2A (PP2A) holoenzyme, modulates substrate specificity, subcellular localization, and responsiveness to phosphorylation. The phosphorylated form mediates the interaction between PP2A and AKT1, leading to AKT1 dephosphorylation.
Subunit / interactions. Component of the serine/threonine-protein phosphatase 2A complex (PP2A). This complex consists of a common heterodimeric core enzyme, composed of a 36 kDa catalytic subunit (subunit C) and a 65 kDa constant scaffold 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. Interacts with SGO1. Interacts with AKT1. Interacts with CUL3 and KLHL15; this interaction leads to proteasomal degradation.
Subcellular location. Cytoplasm.
Tissue specificity. Highest expression in brain.
Post-translational modifications. Ubiquitinated by E3 CUL3-KLHL15 complex; this modification leads to proteasomal degradation.
Induction. By retinoic acid; in neuroblastoma cell lines.
Similarity. Belongs to the phosphatase 2A regulatory subunit B56 family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 32 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
