Predicted to enable GTP binding activity and epidermal growth factor receptor binding activity. Involved in brain development; epidermal growth factor receptor signaling pathway; and response to axon injury. Predicted to be located in several cellular components, including Golgi apparatus; dendritic spine; and ruffle membrane. Predicted to be active in cytoplasm; glutamatergic synapse; and plasma membrane. Orthologous to human ARF4 (ADP ribosylation factor 4). [provided by Alliance of Genome Resources, Apr 2022]
