Enables G-protein beta/gamma-subunit complex binding activity; phosphatidylinositol phospholipase C activity; and phospholipid binding activity. Involved in detection of chemical stimulus involved in sensory perception of bitter taste and phospholipase C-activating G protein-coupled receptor signaling pathway. Located in Golgi apparatus; cytosol; and plasma membrane. Part of G-protein beta/gamma-subunit complex. Orthologous to human PLCB2 (phospholipase C beta 2).
