Western blot - Anti-PPP2R1B antibody [EPR10158] - BSA and Azide free (AB249122)

This data was developed using the same antibody clone in a different buffer formulation (ab154815).

Lanes 1-4 : Merged signal (red and green). Green - ab154815 observed at 66 kDa. Red - loading control ab8245 observed at 36 kDa.

ab154815 Anti-PPP2R1B antibody [EPR10158] was shown to specifically react with PPP2R1B in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266729 (knockout cell lysate ab258133) was used. Wild-type and PPP2R1B knockout samples were subjected to SDS-PAGE. ab154815 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated at room temperature for 2.5 hours at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

The protein PPP2R1B also known as Protein Phosphatase 2 Scaffold Subunit A beta isoform acts as a scaffold for the assembly of PP2A complexes. PPP2R1B has a molecular mass of approximately 66 kDa. The protein expresses widely across various tissues with notable presence in the brain heart and skeletal muscle. As a scaffold subunit PPP2R1B coordinates the structural integrity necessary for phosphatase activity by recruiting regulatory and catalytic subunits important to its function.
Biological function summary

PPP2R1B integrates into the PP2A holoenzyme complex a major serine/threonine phosphatase. This complex regulates numerous cellular processes including cell growth division and signal transduction. PPP2R1B plays a role in maintaining cellular homeostasis through its regulatory activities. By doing so it links to various signaling events some of which control oncogenes and tumor suppressors demonstrating the protein's influence over cell cycle regulation and apoptosis.

Pathways

PPP2R1B plays a significant role in the Raf/MEK/ERK signaling pathway and the PI3K/AKT pathway. Through these pathways PPP2R1B interacts with PDPK1 and AKT1 modulating their phosphorylation status and thereby affecting cell proliferation and survival. By influencing such pathways PPP2R1B helps determine cellular responses to external stimuli impacting processes like differentiation and metabolism that are vital for organismal function.

PPP2R1B links to cancer and Alzheimer's disease. Mutations or downregulation in PPP2R1B have been implicated in colorectal cancer where it alters the PP2A activity and allows unregulated cellular proliferation. In Alzheimer's disease PPP2R1B's interaction with tau protein goes awry contributing to neurofibrillary tangle formation. These connections highlight the importance of PPP2R1B in understanding the molecular basis of these diseases and potential therapeutic targets.
