====== Rac ======

Rac is a subfamily of the [[Rho]] family of [[GTPase]]s, small (~21 kDa) signaling [[G protein]]s (more specifically a GTPase).

The subgroup include:

Rac1.
    
[[Rac2]].
    
Rac3
    
RhoG

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

Results strongly suggest that Rac acts as a positive regulator of the [[PAR]]-elicited release of phosphorylated-HSP27 from human platelets via p38 MAPK but not JNK
