Internalization and molecular processing of insulin receptors in isolated rat adipocytes.


The cellular fate of insulin receptors in isolated rat adipocytes was studied by using a biologically active photosensitive insulin derivative, B2(2-nitro-4-azidophenylacetyl)-des-PheB1-insulin (NAPA-DP-insulin), to photoaffinity label the insulin receptors. Insulin receptors specifically labeled with 125I-labeled NAPA-DP-insulin were identified by NaDodSO4… (More)
