title: Photoaffinity labeling of atrial natriuretic factor receptors of rat kidney cortex plasma membranes.
abstract: Synthetic rat atrial natriuretic factor (ANF) was derivatized with the N-hydroxysuccinimide ester of [125I]iodoazidosalicylic acid to yield a radioactive photoaffinity probe. Incubation of purified plasma membranes from rat kidney cortex with this photoaffinity probe resulted in the specific labeling of a 140-kDa glycoprotein. The photoaffinity labeling of this protein was inhibited by ANF but not by reduced and alkylated ANF nor by other unrelated peptides. A 140-kDa band was also specifically labeled in liver plasma membranes but not in adipocyte plasma membranes. These observations suggest strongly that the 140-kDa glycoprotein is the ANF receptor.
