They are also known as Immunoglobulins. The use of the term antibody …specific adaptive immune response. Two distinct types of molecules are involved in this process – the immuno-globulins and the T-cell antigen receptors (TCRs). Diversity and heterogeneity are characteristic features of these molecules. In both cases there is evidence of extensive gene rearrangements which generate immunoglobulins or TCRs Globular proteins are haemoglobin, insulin, actin and amylase. Haemoglobin transfers oxygen from the lungs to cells, giving the blood its red colour. Insulin is a hormone that helps to regulate blood glucose levels.

Proteins have different shapes and molecular weights; some proteins are globular in shape whereas others are fibrous in nature. For example, hemoglobin is a globular protein, but collagen, found in our skin, is a fibrous protein.The antibody receptor (BCR) is mutated within daughter cells. Many of these mutations bind the antigen worse than the parent antibody, and cells producing these antibodies die. Some antibodies bind the antigen better than the parent, and these cells live. Antibody production starts in specialized immune system tissues.The unique ability of antibodies to specifically recognise and bind with high affinity to virtually any type of antigen, made them interesting molecules for medical and scientific research.

As discussed in Chapter 12, newly synthesized proteins enter the biosynthetic- secretory pathway in the ER by crossing the ER membrane from the cytosol. During their subsequent transport, from the ER to the Golgi apparatus and from the Golgi apparatus to the cell surface and elsewhere, these proteins pass through a series of compartments, where they are successively modified.The five primary classes of immunoglobulins are IgG, IgM, IgA, IgD, and IgE. These are distinguished by the type of heavy chain found in the molecule.
