Enables insulin receptor binding activity; phospholipase C activity; and phosphoprotein binding activity. Involved in several processes, including inositol trisphosphate biosynthetic process; regulation of store-operated calcium channel activity; and response to morphine. Located in clathrin-coated vesicle. Colocalizes with neuron projection. Orthologous to human PLCG1 (phospholipase C gamma 1). [provided by Alliance of Genome Resources, Apr 2022]
