GABRR2 (P28476) - Overview - Molecular Target Synopsis

Protein


GABRR2, Gamma-aminobutyric acid receptor subunit rho-2
UniProt P28476

Also Known as GBRR2_HUMAN, GABRR2

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. Rho-2 GABA receptor could play a role in retinal neurotransmission. Generally pentameric. There are five types of GABA(A) receptor chains: alpha, beta, gamma, delta, and rho. Interacts with SQSTM1.
