Mar 30 2005 Coronin 1 is a member of the coronin protein family specifically expressed in leukocytes and accumulates at sites of rearrangements of the F actin cytoskeleton. Here we describe that coronin 1 molecules are coiled coil mediated homotrimeric complexes which associate with the plasma membrane and with the cytoskeleton via two distinct domains.
