Background: The p21-activated kinases (PAKs) belong to the group of serine/threonine protein kinases and are subdivided into two groups, PAK1-3 (group I) and PAK4-6 (group II), based on sequence similarities and an autoinhibitory domain which is present in group I, but not group II PAK. PAKs in general have similar structural organization, including an N-terminal regulatory domain containing a p21 binding domain (PBD) and an auto-inhibitory domain (AID), and a C-terminal catalytic domain. Binding of Cdc42/Rac1 to PAK2 changes its conformation relieves the auto-inhibition, frees the kinase domain and resulting in its activation. Additionally, apoptotic stimuli lead to caspase-mediated cleavage of PAK2, generating a constitutively active kinase fragment p34 and an N-terminal regulatory fragment p27. PAK2 is the major PAK expressed in T cells and is an essential regulator that drives the actin cytoskeleton-dependent signaling for normal thymocyte development and maturation. Furthermore, PAK2 negatively modulate TGF-β signaling by association with Smad2 and Smad3 in a kinase activity-dependent manner and thereby blocking their activation.
