Abstract:
The coxsackievirus and adenovirus receptor (CAR) mediates entry of coxsackievirus and adenovirus. CAR possesses an extracellular region that is comprised of 2 immunoglobulin domains termed CAR-D1 and CAR-D2. In the present work, the solution structure of CAR-D2, consisting of residues 142-235 of human CAR, has been determined by NMR spectroscopy. CAR-D2 is shown to be a beta-sandwich motif comprised of two beta-sheets, which are stabilized by two disulfide bonds. The first beta-sheet is comprised of beta-strands A, B, and E, and the second beta-sheet is comprised of beta-strands C, F, and G. A relatively hydrophobic helix is found between beta-strands C and E, which replaces beta-strand D of the classical c-type immunoglobulin fold.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
