Specific, saturable EGF receptors were demonstrated in isolated rat pancreatic acini. Binding of EGF to these receptors was one-half maximal at 20 min and maximal at 120 min. Scatchard analyses revealed a single order of binding sites with a Kd of 4.90 nM. Following binding, EGF was rapidly internalized and converted to two acidic species. EGF did not alter either basal amylase release or the rate of [3H]phenylalanine incorporation into TCA-precipitable protein. The finding of high affinity EGF receptors in pancreatic acinar cells supports the hypothesis that EGF participates in the long-term regulation of pancreatic exocrine function.
