Chrnb4 - cholinergic receptor nicotinic beta 4 subunit

Enables acetylcholine binding activity and heterocyclic compound binding activity. Predicted to be involved in several processes, including chemical synaptic transmission; positive regulation of transmission of nerve impulse; and regulation of membrane potential. Predicted to act upstream of or within several processes, including behavioral response to nicotine; smooth muscle contraction; and synaptic transmission involved in micturition. Located in neuron projection and plasma membrane. Part of acetylcholine-gated channel complex. Orthologous to human CHRNB4 (cholinergic receptor nicotinic beta 4 subunit).
