GABA(A) Receptors are ionototropic γ-aminobutyric acid type A receptors. Most of the fast inhibitory synaptic transmissions in the brain are mediated by these ligand-gated ion channels in response in to γ-aminobutyric binding. To date 19 GABA(A) Receptors have been cloned in the mammalian central nervous system (CNS) and are classified by their sequence identity into 7 different subunits (α, β, γ, δ, ε, π, and θ). They consist of pentameric structures assembled by different subunits which are mainly permeable to Cl-that act to reduce neuronal excitation. Alomone Labs is pleased to offer peptide toxins which affect a variety of GABA(A) receptors, conjugated to biotin.
