Predicted to enable G protein-coupled GABA receptor activity and protein heterodimerization activity. Predicted to be involved in gamma-aminobutyric acid signaling pathway and neuron-glial cell signaling. Predicted to act upstream of or within G protein-coupled receptor signaling pathway. Located in cytoplasm and neuron projection. Is expressed in brain; lens; lens epithelium; lens fiber; and lens vesicle. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 59 and nicotine dependence. Orthologous to human GABBR2 (gamma-aminobutyric acid type B receptor subunit 2).
