CRYSTAL STRUCTURE OF THE HUMAN P21-ACTIVATED KINASE 6
|
OverviewOverview
p21-activated kinases have been classified into two groups based on their, domain architecture. Group II PAKs (PAK4-6) regulate a wide variety of, cellular functions, and PAK deregulation has been linked to tumor, development. Structural comparison of five high-resolution structures, comprising all active, monophosphorylated group II catalytic domains, revealed a surprising degree of domain plasticity, including a number of, catalytically productive and nonproductive conformers. Rearrangements of, helix alphaC, a key regulatory element of kinase function, resulted in an, additional helical turn at the alphaC N terminus and a distortion of its C, terminus, a movement hitherto unseen in protein kinases. The observed, structural changes led to the formation of interactions between conserved, ... [(full description)]
