Predicted to enable PDZ domain binding activity; enzyme binding activity; and guanyl-nucleotide exchange factor activity. Predicted to be involved in cell chemotaxis; negative regulation of vascular associated smooth muscle contraction; and positive regulation of vascular associated smooth muscle cell migration. Predicted to be located in several cellular components, including Golgi apparatus; nucleolus; and stereocilium. Orthologous to human DOCK4 (dedicator of cytokinesis 4).
