4-aminobutanoate signaling pathway, 4-aminobutanoate signalling pathway, 4-aminobutyrate signaling pathway, 4-aminobutyrate signalling pathway, GABA signaling pathway, GABA signalling pathway, gamma-aminobutyric acid signalling pathway

The series of molecular signals generated by the binding of gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms, to its receptor on the surface of a target cell.
