The Ras-related GTPases are small, 20- to 25-kDa proteins which cycle between an inactive GDP-bound form and an active GTP-bound state. The Ras superfamily includes the Ras, Rho, Ran, Arf, and Rab/YPT1 families, each of which controls distinct cellul

Previously we found that negatively charged residues at positions 62, 63, and 69 of H-Ras are involved in binding to the CDC25 guanine nucleotide exchange factor (GEF). Using site-directed mutagenesis, we have changed conserved, positively charged re

Ras proteins are activated in vivo by guanine nucleotide exchange factors encoded by genes homologous to the CDC25 gene of Saccharomyces cerevisiae. We have taken a combined genetic and biochemical approach to probe the sites on Ras proteins importan

The yeast Saccharomyces cerevisiae CDC25 gene encodes a nucleotide-exchange-factor (NEF) that can convert the inactive GDP-bound state of RAS proteins to an active RAS-GTP complex. CDC25 can activate the yeast RAS proteins as well as the human H-ras

Mitogen stimulation of cytoskeletal changes and c-jun amino-terminal kinases is mediated by Rac small guanine nucleotide-binding proteins. Vav, a guanosine diphosphate (GDP)–guanosine triphosphate (GTP) exchange factor for Rac that stimulates the e

Vav is a member of a family of oncogene proteins that share an approximately 250-amino-acid motif called a Dbl homology domain. Paradoxically, Dbl itself and other proteins containing a Dbl domain catalyze GTP-GDP exchange for Rho family proteins, wh

While Ras proteins are activated by stimulated GDP release, which enables acquisition of the active GTP-bound state, little is known about how guanine nucleotide exchange factors (GEFs) interact with Ras to promote this exchange reaction. Here we rep
