Figure 1From: Down-regulation of the alpha-2C adrenergic receptor: involvement of a serine/threonine motif in the third cytoplasmic loopThe sequence of the third intracellular loop of the opossum alpha-2C adrenergic receptor. The sequence of the two mutated receptors created by site-directed mutagenesis are indicated. Potential phosphorylation sites (serine and threonine residues) are shown in red.Back to article page
