Immunology, hematology. Heavy chain disease is a form of paraproteinemia and plasma cell dyscrasia that involves the proliferation of cells producing immunoglobulin heavy chains. [1] This disease is characterized by an excessive production of heavy chains that are short and truncated. These heavy chain disease proteins have various deletions ...
The immunoglobulin heavy chain (IgH) is the large polypeptide subunit of an antibody (immunoglobulin). In human genome, the IgH gene loci are on chromosome 14. A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains. Several different types of heavy chain exist that define the class or isotype of an antibody.
Heavy-chain antibody. A heavy-chain antibody is an antibody which consists only of two heavy chains and lacks the two light chains usually found in antibodies. In common antibodies, the antigen binding region consists of the variable domains of the heavy and light chains (V H and V L). Heavy-chain antibodies can bind antigens despite having ...
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
View/Edit Mouse. NADPH oxidase 2 (Nox2), also known as cytochrome b (558) subunit beta or Cytochrome b-245 heavy chain, is a protein that in humans is encoded by the NOX2 gene (also called CYBB gene). [ 5 ] The protein is a superoxide generating enzyme which forms reactive oxygen species (ROS).
Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. [ 6 ] Often, no symptoms are noticed initially. [ 10 ] As it progresses, bone pain, anemia, renal insufficiency, and infections may occur. [ 10 ]
Colors are: H-chains (blue and light blue), L-chains (red and light red), J-chain (magenta) and the secretory component (yellow). Coordinates of each backbone carbon atom were derived PDB entry 3cm9. [ 2 ] Immunoglobulin A (Ig A, also referred to as sIgA in its secretory form) is an antibody that plays a role in the immune function of mucous ...
Clathrin. Clathrin is a protein that plays a major role in the formation of coated vesicles. Clathrin was first isolated by Barbara Pearse in 1976. [1] It forms a triskelion shape composed of three clathrin heavy chains and three light chains. When the triskelia interact they form a polyhedral lattice that surrounds the vesicle.
