Anti-EREG Picoband Antibody

  • WB - Anti-EREG Picoband Antibody ABO12550
    Western blot analysis of EREG expression in human placenta extract (lane 1) and HEPG2 whole cell lysates (lane 2). EREG at 20KD was detected using rabbit anti- EREG Antigen Affinity purified polyclonal antibody (Catalog # ABO12550) at0.5 ??g/mL. The blot was developed using chemiluminescence (ECL) method .

Protein Information
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).

Epiregulin (EPR) is a protein that in humans is encoded by the EREG gene. It is mapped to 4q13.3. This gene encodes a secreted peptide hormone and member of the epidermal growth factor (EGF) family of proteins. The encoded protein is a ligand of the epidermal growth factor receptor (EGFR) and the structurally related erb-b2 receptor tyrosine kinase 4 (ERBB4). Also, it may be involved in a wide range of biological processes including inflammation, wound healing, oocyte maturation, and cell proliferation. Additionally, the encoded protein may promote the progression of cancers of various human tissues.
