The beta 2-adrenergic receptors from hamster, guinea pig, and rat lungs have been solubilized with digitonin and purified by sequential Sepharose-alprenolol affinity and high-performance steric-exclusion liquid chromatography. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and autoradiography of iodinated purified receptor preparations reveal a peptide with an apparent Mr of 64 000 in all three systems that coincides with the peptide labeled by the specific beta-adrenergic photoaffinity probe (p-azido-m-[125I]iodobenzyl)carazolol. A single polypeptide was observed in all three systems, suggesting that lower molecular weight peptides identified previously by affinity labeling or purification in mammalian systems may represent proteolyzed forms of the receptor. Purification of the beta-adrenergic receptor has also been assessed by silver staining, iodinated lectin binding, and measurement of the specific activity (approximately 15 000 pmol of [3H]dihydroalprenolol bound/mg of protein). Overall yields approximate 10% of the initial crude particulate binding, with 1-3 pmol of purified receptor obtained/g of tissue. The purified receptor preparations bind agonist and antagonist ligands with the expected beta 2-adrenergic specificity and stereoselectivity. Peptide mapping and lectin binding studies of the hamster, guinea pig, and rat lung beta 2-adrenergic receptors reveal significant similarities suggestive of evolutionary homology.
