B-Globulins

B-globulins (B-cell antigens, B-lymphocyte antigens) are surface immunoglobulin-like blood plasma proteins present on the surface of mature B-lymphocytes and plasma cells, as well as on the marginal zones of granules and in the lysate fraction of the granulocyte cytoplasm.

B-globulin is a number of different genes that encode a single peptide responsible for the structure and function of the molecule. The core gene encodes the main chain of a protein molecule, usually present separately from the side chain genes. Side chain genes are located on the outside of the chromosome and encode side chains and
