Predicted to enable G protein-coupled amine receptor activity; amine binding activity; and heterocyclic compound binding activity. Predicted to be involved in several processes, including G protein-coupled receptor signaling pathway; learning or memory; and regulation of secretion. Predicted to act upstream of or within G protein-coupled receptor signaling pathway. Predicted to be located in myelin sheath; neuron projection; and plasma membrane. Predicted to be active in dendrite and synapse. Predicted to be integral component of plasma membrane. Is expressed in brain. Orthologous to human HRH3 (histamine receptor H3).
