Antiphosphotyrosine recovery of phospholipase C activity after EGF treatment of A-431 cells

MI Wahl, TO Daniel, and G Carpenter

Department of Biochemistry, Vanderbilt University School of Medicine, Nashville, TN 37232.

A tenfold increase in phospholipase C activity specific for phosphatidylinositol 4,5-bisphosphate (PIP2) was immunopurified from extracts of A-431 epidermoid carcinoma cells stimulated with epidermal growth factor. This finding suggests a biochemical link between growth factor-stimulated tyrosine kinase activity and PIP2 hydrolysis.
