| - | + | [https://www.uniprot.org/uniprot/CDC42_HUMAN CDC42_HUMAN] Plasma membrane-associated small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses. Involved in epithelial cell polarization processes. Regulates the bipolar attachment of spindle microtubules to kinetochores before chromosome congression in metaphase. Plays a role in the extension and maintenance of the formation of thin, actin-rich surface projections called filopodia. Mediates CDC42-dependent cell migration.<ref>PMID:14978216</ref> <ref>PMID:15642749</ref> <ref>PMID:17038317</ref> | |

| - | Cdc42Hs is a member of the Ras superfamily of GTPases and initiates a cascade that begins with the activation of several kinases, including p21-activated kinase (PAK). We have previously used a 46 amino acid fragment of PAK (PBD46) to define the binding surface on Cdc42Hs [Guo et al. (1998) Biochemistry 37, 14030-14037]. Here we describe the three-dimensional solution structure of the Cdc42Hs. GMPPCP-PBD46 complex. Heteronuclear NMR methods were used to assign resonances in the complex, and approximately 2400 distance and dihedral restraints were used to calculate a set of 20 structures using a combination of distance geometry, simulated annealing, and chemical shift and Ramachandran refinement. The overall structure of Cdc42Hs in the complex differs from the uncomplexed structure in two major aspects: (1) the first alpha helix is reoriented to accommodate the binding of the peptide and (2) the regions corresponding to switch I and switch II are less disordered. As suggested by our previous work (Guo et al., 1998) and similar to the complex between Cdc42Hs and fACK [Mott et al. (1999) Nature 399, 384-388], PBD46 forms an intermolecular beta-sheet with beta2 of Cdc42Hs and contacts both switch I and switch II. The extensive binding surface between PBD46 and Cdc42Hs can account for both the high affinity of the complex and the inhibition by PBD46 of GTP hydrolysis. | ||
