Human/Mouse/Rat PP2A Catalytic Subunit Antibody Summary

Species Reactivity

Human, Mouse, Rat

Specificity

Detects endogenous human, mouse, and rat PP2A in Western blots. Because PP2A-alpha and PP2A-beta catalytic subunits are identical in the region used for the immunogen, it is expected that both isoforms will be detected by the antibody.

Source

Monoclonal Rat IgG_2B Clone # 234529

Purification

Protein A or G purified from hybridoma culture supernatant

Immunogen

E. coli-derived recombinant human PP2A-alpha catalytic subunit
Trp209-Leu309
Accession # P67775

Detection of Human and Mouse PP2A Catalytic Subunit, by Western Blot. Western blot shows lysates of U937 human histiocytic lymphoma cell line and C2C12 mouse myoblast cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat PP2A Catalytic Subunit, Monoclonal Antibody (Catalog # MAB1653) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for PP2A Catalytic Subunit, at approximately 36 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: PP2A

Protein Phosphatase 2A (PP2A) dephosphorylates serine and threonine residues in proteins. This ubiquitously expressed enzyme plays a critical role in modulating cell survival, growth factor responses, and neurotransmission. Phosphorylation near the C-terminus at Y307 of the catalytic subunit decreases the phosphatase activity of PP2A and reduces its ability to bind to proteins such as CD28 and the glutamate receptor GluR5. Phosphorylation of PP2A at Y307 is highest during M-phase and lowest during S-phase of the cell cycle. Transient PP2A phosphorylation at this site is also observed in growth factor-stimulated cells.
