Recently, we have obtained evidence in favor of a structural interaction between the epidermal growth factor (EGF) receptor and the Triton X-100-insoluble cytoskeleton of epidermoid carcinoma A431 cells. Here we present a further analysis of the properties of EGF receptors attached to the cytoskelet
## Abstract The metabolism of the receptor for epidermal growth factor (EGF) in Aβ431 cells has been measured by labeling the receptor in vivo with radioactive amino acid precursors and then determining, by immunoprecipitation with specific antiβEGF receptor antisera, the rate of degradation of the
A rapid method for the purification of plasma membrane from a relatively small number of A431 cells is described. The method is a simple, two-step differential centrifugation in the presence of Ca2+ that requires a total centrifugation time of 7 min. The membrane preparations contained a high level
We have studied the synthesis and oligosaccharide processing of the 110,000 dalton form of the epidermal growth factor (EGF) receptor that is secreted into the medium of A-431 cells. Its 90,000 dalton precursor is soluble within the lumen of intracellular membrane vesicles shortly after synthesis, i
