Predicted to enable calmodulin binding activity and phosphatidylinositol phospholipase C activity. Predicted to be involved in several processes, including memory; phosphatidylinositol-mediated signaling; and release of sequestered calcium ion into cytosol. Predicted to act upstream of or within intracellular signal transduction and lipid catabolic process. Predicted to be active in cytoplasm and nuclear speck. Human ortholog(s) of this gene implicated in Alzheimer's disease; developmental and epileptic encephalopathy 12; and myelodysplastic syndrome. Orthologous to human PLCB1 (phospholipase C beta 1).
