摘要
The atypical Rho GTPase Wrch-1 has been proposed roles in cell migration, focal adhesion dissolution, stress fibre break down and tight junction heterogeneity. A screen for Wrch-1 binding-partners identified the novel RhoGAP protein, ARHGAP30, as a Wrch-1 interactor. ARHGAP30 is related to the Cdc42- and Rac1-specific RhoGAP CdGAP, which was likewise found to bind Wrch-1. In contrast to CdGAP, ARHGAP30 serves as a Rac1- and RhoA-specific RhoGAP. Ectopic expression of ARHGAP30 results in membrane blebbing and dissolution of stress-fibres and focal adhesions. Our data suggest roles for ARHGAP30 and CdGAP in regulation of cell adhesion downstream of Wrch-1.
