PIK3R2(Phosphatidylinositol 3-kinase, regulatory subunit 2), also called p85-Beta, is an enzyme that in humans is encoded by the PIK3R2 gene.
The PIK3R2 gene is mapped on 19p13.11.
The NS1 protein from various influenza strains also bound 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 and p85-beta regulated the function of Xbp1s, a transcription factor that orchestrates the unfolded protein response (UPR) following endoplasmic reticulum (ER) stress.
Overexpression of PIK3R2 in livers of ob/ob mice increased glucose tolerance and reduced blood glucose concentrations.
