mig-2 encodes a member of the RhoG family of GTP-binding proteins; MIG-2 activity is required for migration of Q neuroblasts, HSN neurons, and CAN cells as well as neurite outgrowth and guidance; in regulating Q neuroblast migration and dendrite outgrowth, MIG-2 functions upstream of the ANI-1 anillin to asymmetrically regulate ANI-1 localization, and thus stabilize F-actin, at the leading edge and growth cone; MIG-2 is expressed in early embryos and in adults in the vulva, gonadal distal tip cells, and the sex myoblasts and their descendants.
Enables GTPase activity and protein kinase binding activity. Involved in several processes, including actin cytoskeleton organization; axon guidance; and cell migration. Located in cytoplasm; cytoplasmic side of plasma membrane; and neuron projection. Expressed in several structures, including CAN; HSN; distal tip cell; touch receptor neurons; and vulval cell. Used to study epilepsy. Is an ortholog of human RHOG (ras homolog family member G).
