Enables mitogen-activated protein kinase binding activity. Involved in several processes, including positive regulation of cellular component organization; positive regulation of protein phosphorylation; and positive regulation of vascular associated smooth muscle cell migration. Located in growth cone; membrane raft; and nucleus. Part of protein-containing complex. Colocalizes with actin cytoskeleton; focal adhesion; and microtubule cytoskeleton. Orthologous to human IQGAP1 (IQ motif containing GTPase activating protein 1). [provided by Alliance of Genome Resources, Apr 2022]
