Protein

Phosphatidylinositol 3-kinase regulatory subunit gamma

Gene

Pik3r3

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

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.
