Abstract
Rho family GTPases regulate multiple cellular processes through their downstream effectors, where their activities are stimulated by the guanine nucleotide exchange factors. Here, we report a new member of RhoGEF, WGEF, which has the classical structure of DH-PH domain and a C-terminal SH3 domain. WGEF was shown to activate RhoA, Cdc42, and Rac1 by pulldown assay, and forced expression of WGEF resulted in marked rearrangement of the actin cytoskeleton, which is typically seen by the activation of RhoA, Cdc42, and Rac1. WGEF was highly expressed in intestine and also in liver, heart and kidney, which may suggest the involvement of WGEF in the development and functions of these organs. The expression pattern may also suggest the possible importance of WGEF in the understanding of diseases based on metabolic disorder.Entities:
