Domain (CC)

The effector region is required for activating the Rac-specific guanine nucleotide exchange factor (GEF) activity. It mediates both barbed-end actin capping and actin bundling activities. The capping activity is mediated by an amphipathic helix that binds within the hydrophobic pocket at the barbed ends of actin blocking further addition of actin monomers, while the bundling activity is mediated by a compact 4 helix bundle, which contacts 3 actin subunits along the filament (By similarity).; DOMAIN: The SH3 domain mediates interaction with SHB.
