EGF is a growth factor that stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. It results in cellular proliferation, differentiation, and survival.Additionally, EGF has been shown to inhibit gastric secretion, and to be involved in wound healing. EGF signals through a receptor known as c-erbB, which is a class I tyrosine kinase receptor. This receptor also binds with TGF-α and VGF (vaccinia virus growth factor).\u003c\/p\u003e\u003ch2\u003eBiological significance and function\u003c\/h2\u003e\u003cp\u003eFunctionally, \u003cstrong\u003eEGF\u003c\/strong\u003e mediates intercellular communication in immune and stress-response settings through receptor engagement and downstream transcriptional programs. Experimental systems often use defined protein inputs to disentangle receptor proximal signaling from later transcriptional responses.

This is often suitable for many intracellular enzymes and binding studies, while PTM-dependent targets may show differences when glycosylation or specific disulfide-bond patterns are required. For many extracellular signaling proteins and proteases, disulfide bonding and glycosylation can be important for stability and activity.\u003c\/p\u003e\u003ch2\u003eExpression and purification strategy\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eExpression system:\u003c\/strong\u003e E. coli.
