  • Flow cytometric analysis of PI 3 Kinase p85 beta was done on Hela cells. The cells were fixed, permeabilized and stained with the primary antibody (ET1609-30, 1/50) (blue). After incubation of the primary antibody at room temperature for an hour, the cells were stained with a Alexa Fluor 488-conjugated Goat anti-Rabbit IgG Secondary antibody at 1/1000 dilution for 30 minutes.Unlabelled sample was used as a control (cells without incubation with primary antibody; red).

SEQUENCE SIMILARITIES

Belongs to the PI3K p85 subunit family.

POST-TRANSLATIONAL MODIFICATION

Phosphorylated in response to signaling from activated receptor-type protein kinases. Dephosphorylated by PTPRJ. Dephosphorylated at Tyr-655 by PTPN13. Phosphorylation of Tyr-655 impairs while its dephosphorylation promotes interaction with FBXL2 and SCF(FBXL2)-mediated polyubiquitination.; Ubiquitinated. Polyubiquitination by the SCF(FBXL2) complex probably promotes proteasomal degradation of PIK3R2.

SUBCELLULAR LOCATION

Cytosol, nucleus

FUNCTION

Phosphatidylinositol 3-kinase (PI 3-kinase) is composed of p85 and p110 subunits. p85 lacks PI 3-kinase activity and acts as an adapter, coupling p110 to activated protein tyrosine kinase. Two forms of p85 have been described (p85α and p85β), each possessing one SH3 and two SH2 domains. Various p110 isoforms have been identified. p110α and p110β interact with p85α, and p110α has also been shown to interact with p85β in vitro. p110α expression is restricted to white blood cells. It has been shown to bind p85α and p85β, but it apparently does not phosphorylate these subunits. p110α seems to have the capacity to autophosphorylate. p110α does not interact with the p85 subunits. It has been shown to be activated by α and β heterotrimeric G proteins.
