IGH@. Immunoglobulin heavy locus, also known as IGH, is a region on human chromosome 14 that contains a gene for the heavy chains of human antibodies (or immunoglobulins). Immunoglobulins recognize foreign antigens and initiate immune responses such as phagocytosis and the complement system.
Immunoglobulin E (IgE) is a kind of antibody (or immunoglobulin (Ig)  isotype ) that has only been found in mammals.Monomers of IgE consist of two heavy chains (Îµ chain) and two light chains, with the Îµ chain containing 4 Ig-like constant domains (CÎµ1-CÎµ4).gE primes the IgE-mediated allergic response by binding to Fc receptors found on the surface of mast cells and basophils. Fc receptors are also found on eosinophils, monocytes, macrophages and platelets in humans. There are two types of FcÎµ receptors: 1  FcÎµRI (type I FcÎµ receptor), the high-affinity IgE receptor.
