Amphiregulin is a protein encoded by the AREG gene in humans and is mapped to chromosomal region 4q13-4q21. It is considered as a ligand of the epidermal growth factor receptor (EGFR), a widely expressed transmembrane tyrosine kinase. It acts as a bifunctional cell growth modulator consisting of 78 amino acids. The amino-terminal half of this protein is extremely hydrophilic whereas the carboxyl-terminal half exhibits homology to the epidermal growth factor (EGF) family of proteins. It is mostly expressed in human placenta and ovaries and may have some role in the regulation of normal cell growth. It is synthesized as a membrane-anchored precursor protein and its expression is induced by a plethora of stimuli (that includes inflammatory lipids, cytokines, hormones, growth factors and xenobiotics).

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: Amphiregulin binds to the EGF receptor and activates major intracellular signaling cascades governing cell survival, proliferation and motility. This protein plays an important role in the development and maturation of mammary glands, bone tissue and oocytes. Its expression is mainly associated with different pathological conditions, mostly of inflammatory and/or neoplastic nature. It induces ovarian cancer cell invasion by down-regulating E-cadherin expression.
