Total cell lysates (15µg protein) from Jurkat, HeLa (negative control) and NIH3T3 cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with 17µg/mL purified anti-PIK3R1 (clone W16101A) antibody and competitor’s antibody used at manufactures recommended concentration (upper). Proteins were visualized by chemiluminescence detection using a goat anti-rat-IgG secondary antibody conjugated to HRP for clone W16101A and a donkey anti-rabbit IgG Antibody conjugated to HRP for competitor’s antibody. Direct-Blot™ HRP anti-β-actin Antibody was used as a loading control (lower). Lane M: Molecular Weight ladder.

    NIH3T3 cells were fixed with 4% paraformaldehyde (PFA) for 15 minutes, permeabilized with 0.5% Triton X-100 for 3 minutes, and blocked with 5% FBS for 60 minutes. Then the cells were intracellularly stained with 2 µg/ml anti-PIK3R1 antibody (clone W16101A) overnight at 4°C followed by Alexa Fluor® 594 (red) conjugated goat anti-rat IgG for one hour at room temperature. Nuclei were counterstained with DAPI (blue). The image was captured with a 60X objective.

Description

Phosphatidylinositol 3-kinase (PI3K) is a heterodimer comprised of a catalytic subunit encoded by PIK3CA (p110α) and one of a number of regulatory subunits. PIK3R1, also known as PI3K p85-alpha, is an 85kD regulatory subunit of PI3K. Upon activation of the receptor tyrosine kinases, PI3K phosphorylates inositol lipids to phosphatidylinositol-3,4,5-trisphosphate (PIP3), subsequently leads to activation of AKT and downstream effectors. The PI3K signaling regulates various cellular processes such as protein synthesis, cell growth, cell cycle progression, cell proliferation, angiogenesis, and survival. In addition, PI3K pathway has been found to play important roles in tumorigenesis and cancer progression. PIK3R1 appears to be a tumor suppressor due to its ability to stabilize the catalytic subunit of PI3K. Mutations in PIK3R1 have been associated with the autosomal dominant disorder SHORT syndrome.
