Witryna6 sie 2024 · Each light chain is composed of two immunoglobulin domains, an N-terminal variable (V) domain and a C-terminal constant (C) domain . Structurally, the C- and V-domains share conserved common features. ... Changes in primary structure introduced by somatic hypermutation into the germline sequence or by … Somatic hypermutation (or SHM) is a cellular mechanism by which the immune system adapts to the new foreign elements that confront it (e.g. microbes), as seen during class switching. A major component of the process of affinity maturation, SHM diversifies B cell receptors used to recognize … Zobacz więcej When a B cell recognizes an antigen, it is stimulated to divide (or proliferate). During proliferation, the B-cell receptor locus undergoes an extremely high rate of somatic mutation that is at least 10 –10 fold greater than … Zobacz więcej • Affinity maturation • Anergy • Immune system • V(D)J recombination Zobacz więcej The mechanism of SHM involves deamination of cytosine to uracil in DNA by the enzyme activation-induced cytidine deaminase, or AID.
