IHC staining of purified anti-PPP2R4 (PTPA) antibody (clone 5G3) on formalin-fixed paraffin-embedded human brain tissue. Following antigen retrieval using Sodium Citrate H.I.E.R., the tissue was incubated with 10 µg/ml of the primary antibody for 60 minutes at room temperature. BioLegend's Ultra-Streptavidin (USA) HRP kit (Multi-Species, DAB, Cat. No. 929901) was used for detection followed by hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective.

    Western blot of purified anti-PPP2R4 (PTPA) antibody (clone 5G3). Lane 1: Molecular weight marker; Lane 2: 30 µg of human brain nuclear lysate; Lane 3: 30 µg of mouse brain nuclear lysate. The blot was incubated with 1 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence was used as the detection system.

Description

Protein phosphatase 2A is a heterotrimeric protein serine/threonine phosphatase consisting of a 36-kD catalytic C subunit (alpha and beta isoforms), a 65-kD structural A subunit (alpha and beta isoforms), and a variable regulatory B subunit. When the PP2A catalytic C subunit associates with the A and B subunits several species of holoenzymes are produced with distinct functions and characteristics. Ubiquitously expressed, PP2A is involved in a broad range of cellular processes, including membrane receptor desensitization, signal transduction, intermediary metabolism, transcriptional regulation and control of DNA replication, and mitosis. The PP2A phosphatase family accounts for the majority of Ser/Thr phosphatase activity in the brain and specifically regulates tau phosphorylation, both directly as tau phosphatase and indirectly by regulating the activities of several tau kinases which include CaM Kinase II, PKA, MAP kinase kinase (MEK 1/2), extracellular regulated kinase (ERK 1/2), GSK-3β, and P70S6 kinase, thus regulating tau microtubule binding in the brain. When PP2A B' delta (PP2A 56 kDa regulatory subunit delta isoform) is associated with the A and C subunits, tau protein cannot bind to PP2A and be dephosphorylated, leading to increased tau aggregation.
