amphiregulin production
amphiregulin production
The appearance of amphiregulin due to biosynthesis or secretion following a cellular stimulus, resulting in an increase in its intracellular or extracellular levels. Amphiregulin (AREG) is a ligand of the epidermal growth factor receptor (EGFR), a widely expressed transmembrane tyrosine kinase. AREG is synthesized as a membrane-anchored precursor protein that can engage in juxtacrine signaling on adjacent cells. Alternatively, after proteolytic processing by cell membrane proteases, mainly TACE/ADAM17, AREG is secreted and behaves as an autocrine or paracrine factor.
