Phosphorylation of human growth hormone by the epidermal growth factor-stimulated tyrosine kinase.
In the present study, we have demonstrated that human growth hormone (hGH) can be phosphorylated by the epidermal growth factor (EGF)-stimulated tyrosine kinase of A431 cell membranes. Phosphotyrosine was the predominant phosphoamino acid released from phosphorylated hGH on partial acid hydrolysis. All five tyrosine-containing tryptic peptides of hGH are also phosphorylated by the EGF-stimulate...
متن کامل2D-QSAR and docking studies of 4-anilinoquinazoline derivatives as epidermal growth factor receptor tyrosine kinase inhibitors
Introduction: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor derivatives play an important role in the treatment of cancer. We aim to construct 2D-QSAR models using various chemometrics using 4-anilinoquinazoline-containing EGFR TKIs. In addition, the binding profile of these compounds was evaluated using a docking study. Materials and Methods: In this study, 122 compounds of...
متن کاملPlatelet-derived growth factor-stimulated migration of murine fibroblasts is associated with epidermal growth factor receptor expression and tyrosine phosphorylation.
Previous studies have shown that epidermal growth factor (EGF) synergizes with various extracellular matrix components in promoting the migration of B82L fibroblasts expressing wild-type EGF receptors and that functional EGF receptors are critical for the conversion of B82L fibroblasts to a migratory cell type (). In the present study, we examined the effects of platelet-derived growth factor (...
متن کاملRegulatory control of the epidermal growth factor receptor tyrosine kinase.
The epidermal growth factor (EGF) receptor has been shown to posses an intrinsic tyrosine protein kinase activity that is stimulated by the binding ofEGF [1]. In addition, two other ligands for the EGF receptor can stimulate the tyrosine protein kinase activity in intact cells: TGF-(X (transforming growth factor (X) and a soluble biosynthetic precursor of TGF-(X [2, 3]. Analysis of the kinetics...
متن کاملSelf-phosphorylation enhances the protein-tyrosine kinase activity of the epidermal growth factor receptor.
The effect of self-phosphorylation on the protein-tyrosine kinase activity of the epidermal growth factor receptor has been investigated using immunoaffinity-purified protein. Enzyme was first incubated for various times with excess ATP to phosphorylate it to differing extents; the ability of the enzyme to phosphorylate exogenous peptide substrates was then measured as a function of its self-ph...
