Predicted to enable T cell receptor binding activity and actin filament binding activity. Predicted to contribute to guanyl-nucleotide exchange factor activity. Predicted to be involved in Rho protein signal transduction; positive regulation of ruffle assembly; and regulation of Rho protein signal transduction. Predicted to act upstream of or within Rac protein signal transduction. Predicted to be located in cytosol and ruffle. Predicted to be part of protein-containing complex. Predicted to be active in ruffle membrane. Is expressed in several structures, including alimentary system; central nervous system; immune system; reproductive system; and respiratory system. Orthologous to human EPS8L1 (EPS8 like 1). [provided by Alliance of Genome Resources, Apr 2022]
