GABRA2 (P47869) - Overview - Molecular Target Synopsis

Protein


GABRA2, Gamma-aminobutyric acid receptor subunit alpha-2
UniProt P47869

Also Known as GBRA2_HUMAN, GABRA2

GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel. Generally pentameric. There are five types of GABA(A) receptor chains: alpha, beta, gamma, delta, and rho. Interacts with UBQLN1. Interacts with KIF21B. Interacts with LHFPL4.
