Solubilized proteins of the plasma membrane of bovine adrenal medulla were fractionated on the basis of their affinity for secretory vesicles. The isolation procedure included preparation of a highly purified fraction of plasma membranes, its solubilization in detergent, and application to a column prepared from glutaraldehyde-fixed chromaffin granules. Using this technique, one major polypeptide (80% of the material bound) was isolated. This protein has been shown to originate from the plasma membrane and has no affinity for fixed bovine adrenal medullary mitochondria or lysosomes. It is eluted most effectively by low pH (3.0) and can be rebound and re-eluted from fixed secretory granules. In sodium dodecyl sulfate and beta-mercaptoethanol it has an apparent molecular weight of 51,000. In addition, two minor components, comprising about 20% of the material bound were detected having apparent molecular weights in sodium dodecyl sulfate of 14,000 and 62,000. It is suggested that such a molecule could function as a plasma membrane-located receptor for chromaffin granules during the secretory process.
