Rac (GTPase)

Rac is a subfamily of the Rho family of GTPases,[1] small (~21 kDa) signaling G proteins (more specifically a GTPase). When bound to GTP, Rac is activated. In its activated state, Rac participates in the regulation of cell movement, through its involvement in structural changes to the actin Cytoskeleton.[2]

The subgroup include:

Some research has suggested that Rac could be involved in mediating the process of forgetting.[3][4]
