Predicted to enable fibroblast growth factor receptor binding activity; neurotrophin TRKA receptor binding activity; and transmembrane receptor protein tyrosine kinase adaptor activity. Involved in cellular response to fibroblast growth factor stimulus and positive regulation of vascular associated smooth muscle cell proliferation. Predicted to be located in adherens junction and plasma membrane. Predicted to be active in cell-cell junction and cytoplasm. Orthologous to human FRS2 (fibroblast growth factor receptor substrate 2). [provided by Alliance of Genome Resources, Apr 2022]
