CRYSTAL STRUCTURE OF THE HUMAN IGG1 FC-FRAGMENT,GLYCOFORM (MN2F)2

Overview

Antibodies may be viewed as adaptor molecules that provide a link between, humoral and cellular defence mechanisms. Thus, when antigen-specific IgG, antibodies form antigen/antibody immune complexes the effectively, aggregated IgG can activate a wide range of effector systems. Multiple, effector mechanisms result from cellular activation mediated through a, family of IgG-Fc receptors differentially expressed on leucocytes. It is, established that glycosylation of IgG-Fc is essential for recognition and, activation of these ligands. IgG antibodies predominate in human serum and, most therapeutic antibodies are of the IgG class.The IgG-Fc is a homodimer, of N-linked glycopeptide chains comprised of two immunoglobulin domains, (Cgamma2, Cgamma3) that dimerise via inter-heavy chain disulphide ...
