RAC-2
CELE_K03D3.10, K03D3.10
rac-2 encodes a small Rho family GTPase that, along with CED-10 and MIG-2, is one of three C. elegans Rac-related proteins; genetic studies indicate that rac-2 functions redundantly with mig-2 and ced-10 to regulate CAN and PDE axon pathfinding and CAN cell migration; in addition, rac-2 functions slightly redundant with mig-2 during distal tip cell movement and slightly redundant with ced-10 during cell-corpse phagocytosis; as unc-73 mutations enhance rac-2 defects in axon pathfinding and CAN cell migration, UNC-73/Trio is a likely candidate to act upstream of RAC-2 and positively regulate its GTPase activity in vivo; further, as UNC-115 activity is required to mediate the morphogenetic effects of constitutively active RAC-2(G12V), UNC-115, an actin-binding protein, is likely to be a downstream effector of RAC-2; GFP::RAC-2 reporters expressed in neurons and neuroblasts reveal localization at cell margins and the nerve ring, the latter suggesting that GFP::RAC-2 associates with the axonal plasma membrane.
