PAK2, activated by CDC42 or RAC1 RHO GTPases, phosphorylates myosin regulatory light chain (MRLC, MYL9 or MYL12B) of the non-muscle myosin II complex on threonine residue T19 (also labeled in literature as T18). This leads to the rearrangement of the actin cytoskeleton and cell retraction (Chew et al. 1998, Zeng et al. 2000).
