摘要
The Rho guanine nucleotide exchange factor GEF-H1 is uniquely regulated by microtubule binding and is crucial in coupling microtubule dynamics to Rho-GTPase activation in a variety of normal biological situations. Here, we review the roles of GEF-H1 in epithelial barrier permeability, cell motility and polarization, dendritic spine morphology, antigen presentation, leukemic cell differentiation, cell cycle regulation, and cancer. GEF-H1 might also contribute to pathophysiological signaling involved in leukemias, and in cancers associated with mutated p53 tumor suppressor gene, epithelial and endothelial cell dysfunction, infectious disease, and cardiac hypertrophy. We suggest that GEF-H1 could be a novel therapeutic target in multiple human diseases.
