Gamma-aminobutyric acid receptor subunit delta is a protein that in humans is encoded by the GABRD gene.[4][5][6]


γ-Aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABAA receptors, which are ligand-gated chloride channels. The GABAA receptor is generally pentameric. Its five subunits are alpha, beta, gamma, delta, and rho. The GABRD gene encodes the delta subunit.[6]

Cell type-specific expression[edit]

In a technical comparison between quantitative reverse transcriptase PCR and digital PCR, the expression of the rat gabrd gene was examined across three cell types in the somatosensory cortex: neurogliaform cells, fast spiking basket cells and pyramidal cells.[7] Gene expression was detected in all three cell types, but showed marked enrichment in neurogliaform cells versus the other cell types examined.[7]
