  • IF - PIK3R3 Antibody (C-term) AP8025a
    Fluorescent image of U251 cells stained with PIK3R3 Antibody(C-term) (Cat#AP8025A). AP8025A was diluted at 1:100 dilution. An Alexa Fluor 488-conjugated goat anti-rabbit lgG at 1:400 dilution was used as the secondary antibody (green). Cytoplasmic actin was counterstained with Alexa Fluor® 555 conjugated with Phalloidin (red).
  • WB - PIK3R3 Antibody (C-term) AP8025a
    Western blot analysis of lysate from MDA-MB-453 cell line, using PI3KR3 Antibody (G331)(Cat. #AP8025a. RB1719 was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysate at 35ug per lane.
  • IHC-P - PIK3R3 Antibody (C-term) AP8025a
    Formalin-fixed and paraffin-embedded human hepatocarcinoma tissue reacted with PIK3R3 antibody (C-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

Protein Information
Name PIK3R3
Function Binds to activated (phosphorylated) protein-tyrosine kinases through its SH2 domain and regulates their kinase activity. During insulin stimulation, it also binds to IRS-1.
Tissue Location Highest levels in brain and testis. Lower levels in adipose tissue, kidney, heart, lung and skeletal muscle

PIK3R3 binds to activated (phosphorylated) protein-tyrosine kinases through its SH2 domain and regulates their kinase activity. During insulin stimulation, it also binds to IRS-1. It is a component of a heterodimer of p110 (catalytic) and p55 (regulatory) subunits. The protein is expressed at highest levels in brain and testis. Lower levels are detected in adipose tissue, kidney, heart, lung and skeletal muscle. The protein contains 2 SH2 domains.
