Supplementary information

PPP2R5B also known as Protein Phosphatase 2 Regulatory Subunit B56 Beta is a regulatory subunit of protein phosphatase 2A (PP2A). It has a molecular mass of approximately 56 kDa. This protein is expressed in various tissues with higher expression in the brain heart and skeletal muscle. Its mechanical function involves modulating PP2A activity by directing the phosphatase to specific substrates which impacts diverse cellular processes.
Biological function summary

The subunit modulates several key processes including cell growth division and apoptosis. It serves as part of the PP2A holoenzyme complex a major Ser/Thr phosphatase. This complex influences many signaling pathways by dephosphorylating target proteins. Through interactions with other B subunits the specific regulatory effects of B56 beta become fine-tuned providing this subunit with precise control over cellular outcomes.

Pathways

PPP2R5B plays a role in essential signaling cascades such as the MAPK/ERK and PI3K/AKT pathways. These pathways regulate diverse cell functions including proliferation and survival. PPP2R5B coordinates with other proteins like Bcl-2 and p53 in these pathways to regulate apoptosis and cell cycle progression. Its ability to influence these pathways places it at a pivotal point in the signal transduction network.

Alterations in PPP2R5B function have links to cancer development and Alzheimer’s disease. In cancer its relationship with p53 suggests a role in tumor suppression as PPP2R5B can affect p53 stability. In neurodegenerative contexts such as Alzheimer’s the improper regulation of phosphorylation sites could contribute to pathogenesis again implicating pathways like PI3K/AKT. Identifying PPP2R5B interactions is important for understanding disease mechanisms.

Target data

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.
