Adrenergic α1 Receptors

Adrenergic α1 receptors (α1-adrenoceptors) are members of the adrenergic receptor group of G-protein-coupled receptors that also includes α2A, α2B, α2C, β1, β2 and β3. The adrenergic α1 receptors are further divided into three subtypes: α1A, α1B and α1D receptors.

Adrenergic α1 receptors (α1-adrenoceptors) are members of the adrenergic receptor group of G-protein-coupled receptors that also includes α2A, α2B, α2C, β1, β2 and β3. The adrenergic α1 receptors are further divided into three subtypes: α1A, α1B and α1D receptors. α1-adrenoceptors are widely distributed in both the CNS and periphery where they play a major role in smooth muscle contraction. A fourth α1 receptor subtype has been postulated and is designated as α1L based on its low affinity for prazosin. It has been suggested that this subtype may represent a different conformational state of the α1A subtype.
