  • 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
    modifications

    Polyubiquitinated 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
