Cytoplasm. Endomembrane system. Cell projection, lamellipodium. Cytoplasm, perinuclear region. Cell membrane. Cytoplasm, cytoskeleton. Note=Membrane-associated when activated. Colocalizes with NRBP to endomembranes and at the cell periphery in lamellipodia. Colocalized with CIB1 in the perinuclear area and at the cell periphery.
Plasma membrane-associated small GTPase which cycles between an active GTP-bound and inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses, such as cell spreading and the formation of actin-based protusions including lamellipodia and membrane ruffles. Promotes cell adhesion and spreading on fibrinogen in a CIB1 and alpha-IIb/beta3 integrin-mediated manner. {Experimental EvidencePubMed:11756406, Experimental EvidencePubMed:11956649}.
Neurodevelopmental disorder with structural brain anomalies and dysmorphic facies (NEDBAF) [MIM:618577]: An autosomal dominant neurodevelopmental disorder characterized by global developmental delay, severe intellectual disability, poor language, seizures, dysmorphic features, and thin corpus callosum. {Experimental EvidencePubMed:29276006, Experimental EvidencePubMed:30293988}. Note=The disease is caused by variants affecting the gene represented in this entry.
