Protein Biology

Function

Ligand of the EGF receptor/EGFR and ERBB4. Stimulates EGFR and ERBB4 tyrosine phosphorylation (PubMed:9419975). Contributes to inflammation, wound healing, tissue repair, and oocyte maturation by regulating angiogenesis and vascular remodeling and by stimulating cell proliferation (PubMed:24631357)

Subcellular Location

Cell membrane (Single-pass type I membrane protein)

Tissue Specificity

In normal adults, expressed predominantly in the placenta and peripheral blood leukocytes. High levels were detected in carcinomas of the bladder, lung, kidney and colon

Subunit

Interacts with EGFR and ERBB4

Gene: EREG  |  Organism: Homo sapiens
