General annotation (Comments)

Function

Phosphatidylinositol-3,4,5-trisphosphate-dependent GTPase-activating protein that modulates actin cytoskeleton remodeling by regulating ARF and RHO family members. Is activated by phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3) binding. Can be activated by phosphatidylinositol-3,4-bisphosphate (PtdIns(3,4,5)P2) binding, albeit with lower efficiency. Acts preferentially on ARF5 and on RHOA. Ref.1

Subunit structure

Interacts with INPPL1/SHIP2 By similarity.

Subcellular location

Cytoplasm. Cell membrane; Peripheral membrane protein. Cytoplasmcytoskeleton. Cell projectionlamellipodium. Cell projectionruffle. Note: Cytoplasmic, and associated with F-actin-rich membrane ruffles and lamellipodia. Ref.1

Post-translational modification

Tyrosine phosphorylated at a low basal level. PDGF treatment stimulates phosphorylation. Tyrosine phosphorylation is increased in cells that are in the process of becoming attached to a substrate and that start spreading and flattening. Ref.1 Ref.5

Sequence similarities

Contains 1 Arf-GAP domain.

Contains 5 PH domains.

Contains 1 Ras-associating domain.

Contains 1 Rho-GAP domain.

Contains 1 SAM (sterile alpha motif) domain.

Sequence caution

The sequence AAL78678.1 differs from that shown. Reason: Erroneous initiation.

The sequence BAD90507.1 differs from that shown. Reason: Erroneous initiation.
