Specifications for ErbB-3 (Her-3) Antibody, anti-human, REAfinity™


Clone REA508 recognizes the human ErbB-3 antigen, a single-pass type I membrane protein, which is also known as tyrosine kinase-type cell surface receptor HER3. ErbB-3 is a receptor tyrosine kinase and a member of the epidermal growth factor receptor family (EGFR). It is unique among the ErbB family members in that it is has been shown to have weak or no tyrosine kinase activity. After dimerization with other members of the EGFR family several signal transduction cascades can be activated, including phosphoinosite 3'-kinase (PI3-K)/Akt and extracellular signal-regulated kinase (ERK1/2). ErbB-3 is widely expressed in normal tissues including cells of the gastrointestinal, reproductive, respiratory and urinary tracts, as well as the skin, endocrine, and nervous system. It is expressed at elevated levels in a range of human malignancies.
Additional information: Clone REA508 displays negligible binding to Fc receptors.
