Gene: GABRB3 (gamma-aminobutyric acid type A receptor subunit beta3) Homo sapiens
Symbol: GABRB3
Name: gamma-aminobutyric acid type A receptor subunit beta3
CRRD ID: 736139
Description: Exhibits GABA-A receptor activity; GABA-gated chloride ion channel activity; and identical protein binding activity. Predicted to contribute to chloride channel activity. Involved in several processes, including cellular response to histamine; gamma-aminobutyric acid signaling pathway; and inhibitory synapse assembly. Localizes to GABA-A receptor complex and integral component of plasma membrane. Implicated in childhood absence epilepsy and early infantile epileptic encephalopathy 43.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ECA5; EIEE43; GABA(A) receptor beta-3 subunit; GABA(A) receptor subunit beta-3; GABA(A) receptor, beta 3; GABA-A receptor beta-3 subunit; GABA-alpha receptor beta-2 subunit; GABAA receptor beta-3 subunit; gamma-aminobutyric acid (GABA) A receptor, beta 3; gamma-aminobutyric acid A receptor beta 3; gamma-aminobutyric acid receptor subunit beta-3; gamma-aminobutyric acid type A receptor beta3 subunit; MGC9051
