Predicted to enable 1-phosphatidylinositol-3-kinase regulator activity. Predicted to be involved in negative regulation of epidermal growth factor-activated receptor activity and phosphatidylinositol phosphate biosynthetic process. Predicted to act upstream of or within negative regulation of signal transduction and regulation of growth. Predicted to be located in cytosol. Predicted to be part of phosphatidylinositol 3-kinase complex. Is expressed in ganglia; sensory organ; thymus primordium; and ventricular layer. Orthologous to human SOCS4 (suppressor of cytokine signaling 4). [provided by Alliance of Genome Resources, Apr 2022]
