Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables ligand-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential. Involved in modulation of chemical synaptic transmission. Is active in GABA-ergic synapse; glutamatergic synapse; and presynaptic membrane. Is expressed in brain; cerebral cortex; and retina. Orthologous to human GABRR1 (gamma-aminobutyric acid type A receptor subunit rho1).
