Coiled Coil

Domain (CC)

The IMD domain forms a coiled coil. The isolated domain can induce actin bundling and filopodia formation. In the absence of G-proteins intramolecular interaction between the IMD and the SH3 domain gives rise to an auto-inhibited state of the protein. Interaction of the IMD with RAC1 or CDC42 leads to activation.; DOMAIN: The SH3 domain interacts with ATN1, ADGRB1, WASF1, WASF2, SHANK1, DIAPH1 and ENAH.
