As part of the DISP complex, may regulate the association of septins with actin and thereby regulate the actin cytoskeleton. Component of the DOCK7-induced septin displacement/DISP complex, at least composed of DOCK7, LRCH3 and MYO6. Predicted to contain a signal peptide and to be secreted. However, this is not consistent with an interaction with DOCK7 and MYO6 and the suggested function in cytoskeleton organization.
