Enables GABA receptor binding activity. Predicted to be involved in negative regulation of cold-induced thermogenesis and phosphatidylinositol-mediated signaling. Predicted to act upstream of or within several processes, including gamma-aminobutyric acid signaling pathway; regulation of GABAergic synaptic transmission; and regulation of peptidyl-serine phosphorylation. Predicted to be located in plasma membrane. Orthologous to human PLCL1 (phospholipase C like 1 (inactive)). [provided by Alliance of Genome Resources, Apr 2022]
