Description: Phosphatidylinositol 3-kinase regulatory subunit 2, also called p85-Beta, PIK3R2 and PIK3, is an enzyme that in humans is encoded by the PIK3R2 gene. The NS1 protein from various influenza strains bind p85-beta, but not p85-alpha. Binding of p85-beta and activation of PI3K required tyr89 of NS1, and mutant viruses expressing NS1 with a tyr89-to-phe substitution grew more slowly in cell culture than wildtype viruses. Using mouse embryonic fibroblasts, Park et al. showed that, in addition to regulating PI3K function, p85-alpha/beta regulated the function of Xbp1s, a transcription factor that orchestrates the unfolded protein response (UPR) following endoplasmic reticulum (ER) stress. Overexpression of the protein in livers of ob/ob mice increased glucose tolerance and reduced blood glucose concentrations.
Immunogen: Amino acids 447-461 (KVYHQQYQDKSREYD-beta specific) was used as the immunogen for this PI3K antibody (100% human, mouse and rat homology).
Storage: After reconstitution, the PI3K antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20 °C. Avoid repeated freezing and thawing.
