Structure of Antibody. Primary Protein Structure: Successive amino acids forming the backbone of a polypeptide chain are linked together through peptide bonds and it is believed that these are the only covalent associations […] G protein-coupled receptors (GPCRs) represent the largest protein family encoded by the human genome. IgD 4. The intracellular domain consists of two domains, only one of which has intrinsic kinase activity. IgG is the only class of immunoglobulin that can cross the placenta in humans, and it is largely responsible for protection of the newborn during the first months of life. Even with treatment survival is poor, making pHGG the number one cause of cancer death in children.
