Background Information

The p21-Activated kinase 1 (PAK1), a member of serine-threonine kinases family, was initially identified as an interactor of the Rho GTPases RAC1 and CDC42, which affect a wide range of processes associated with cell motility, survival, metabolism, cell cycle, proliferation, transformation, stress, inflammation, and gene expression(PMID: 32863957). PAK1 is over-expressed in various malignancies such as ovarian, breast, lung, and bladder cancers, and is closely associated with tumor invasion.
