Enables small GTPase binding activity. Involved in cellular response to growth factor stimulus; positive regulation of protein kinase activity; and transmembrane receptor protein tyrosine kinase signaling pathway. Acts upstream of or within fibroblast migration; negative regulation of dephosphorylation; and regulation of cytokine production. Located in several cellular components, including cortical actin cytoskeleton; focal adhesion; and lateral plasma membrane. Part of ribonucleoprotein complex. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and skin. Orthologous to human IQGAP1 (IQ motif containing GTPase activating protein 1). [provided by Alliance of Genome Resources, Apr 2022]
