Target
-
Function
Binds to activated (phosphorylated) protein-Tyr kinases, through its SH2 domain, and acts as an adapter, mediating the association of the p110 catalytic unit to the plasma membrane. Necessary for the insulin-stimulated increase in glucose uptake and glycogen synthesis in insulin-sensitive tissues. -
Tissue specificity
Isoform 2 is expressed in skeletal muscle and brain, and at lower levels in kidney and cardiac muscle. Isoform 2 and isoform 4 are present in skeletal muscle (at protein level). -
Sequence similarities
Belongs to the PI3K p85 subunit family.
Contains 1 Rho-GAP domain.
Contains 2 SH2 domains.
Contains 1 SH3 domain. -
Domain
The SH3 domain mediates the binding to CBLB, and to HIV-1 Nef. -
Post-translational
modificationsPolyubiquitinated in T-cells by CBLB; which does not promote proteasomal degradation but impairs association with CD28 and CD3Z upon T-cell activation.
Phosphorylated. Dephosphorylated by PTPRJ. - Information by UniProt

Western blot - Anti-PI 3 Kinase p85 alpha antibody [EPR5513] (ab133595)Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: PI 3 Kinase p85 alpha knockout HAP1 cell lysate (20 µg)
Lane 3: Jurkat cell lysate (20 µg)
Lane 4: THP1 cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab133595 observed at 90 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab133595 was shown to specifically react with PI 3 Kinase p85 alpha when PI 3 Kinase p85 alpha knockout samples were used. Wild-type and PI 3 Kinase p85 alpha knockout samples were subjected to SDS-PAGE. ab133595 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging. -
