功能GTPase signaling protein that binds to and hydrolyzes GTP. Regulates signaling pathways involving G-proteins-coupled receptor and heterotrimeric proteins such as GNB1, GNB2 and GNB3. May be involved in selected striatal competencies, mainly locomotor activity and motor coordination.
组织特异性Pancreatic endocrine cells (islets of Langerhans).
序列相似性Belongs to the small GTPase superfamily. RasD family.
翻译后修饰Farnesylated. Farnesylation is required for membrane targeting.
