Cell migration requires the coordinated spatiotemporal regulation of actomyosin contraction and cell protrusion/adhesion. Nonmuscle myosin II (MII) controls Rac1 and Cdc42 activation, and cell protrusion and focal complex formation in migrating cells. However, these mechanisms are poorly understood. Here, we show that MII interacts specifically with(More)
BACKGROUND Non-muscle myosin II (NM II) regulates a wide range of cellular functions, including neuronal differentiation, which requires precise spatio-temporal activation of Rho GTPases. The molecular mechanism underlying the NM II-mediated activation of Rho GTPases is poorly understood. The present study explored the possibility that NM II regulates(More)
We previously showed that p21-activated kinase 2 (PAK2), a major PAK isoform expressed in PC12 cells, mediates neurite outgrowth via Rac1 GTPase. RhoGDI1 forms a complex with Rac1, resulting in its inhibition. Rac1 activation requires dissociation from RhoGDI1. Here, we show that PAK2 mediates basic fibroblast growth factor (bFGF)-stimulated neurite(More)
p21-activated kinases (PAKs) are key regulators of actin dynamics, cell proliferation and cell survival. Deregulation of PAK activity contributes to the pathogenesis of various human diseases, including cancer and neurological disorders. Using an ELISA-based screening protocol, we identified naphtho(hydro)quinone-based small molecules that allosterically(More)
