Epiregulin Protein, Human (HEK293, Fc)

Epiregulin Protein, a ligand for EGFR and ERBB4, crucially influences inflammation, wound healing, tissue repair, and oocyte maturation. It stimulates tyrosine phosphorylation of both receptors, regulating angiogenesis, vascular remodeling, and cell proliferation. Interactions with EGFR and ERBB4 contribute to intricate signaling pathways, essential for diverse physiological responses and cellular functions. Epiregulin Protein, Human (HEK293, Fc) is the recombinant human-derived Epiregulin protein, expressed by HEK293 , with N-hFc labeled tag. The total length of Epiregulin Protein, Human (HEK293, Fc) is 46 a.a., with molecular weight of ~35 kDa.

Epiregulin, a ligand for the EGF receptor (EGFR) and ERBB4, plays a crucial role in cellular processes such as inflammation, wound healing, tissue repair, and oocyte maturation. It achieves this by stimulating the tyrosine phosphorylation of both EGFR and ERBB4. Additionally, epiregulin is involved in the regulation of angiogenesis, vascular remodeling, and cell proliferation. Through its interactions with EGFR and ERBB4, epiregulin contributes to intricate signaling pathways that are essential for various physiological responses and cellular functions.
