>cd04130 Wrch_1 Wrch-1 subfamily. Wrch-1 (Wnt-1 responsive Cdc42 homolog) is a Rho family GTPase that shares significant sequence and functional similarity with Cdc42. Wrch-1 was first identified in mouse mammary epithelial cells, where its transcription is upregulated in Wnt-1 transformation. Wrch-1 contains N- and C-terminal extensions relative to cdc42, suggesting potential differences in cellular localization and function. The Wrch-1 N-terminal extension contains putative SH3 domain-binding motifs and has been shown to bind the SH3 domain-containing protein Grb2, which increases the level of active Wrch-1 in cells. Unlike Cdc42, which localizes to the cytosol and perinuclear membranes, Wrch-1 localizes extensively with the plasma membrane and endosomes. The membrane association, localization, and biological activity of Wrch-1 indicate an atypical model of regulation distinct from other Rho family GTPases. Most Rho proteins contain a lipid modification site at the C-terminus,
