WebThe immunoglobulin (Ig) repertoire achieves functional diversification through several somatic alterations of the Ig locus. One of these processes, somatic hypermutation … Als somatische Hypermutation (SHM) wird das Einfügen von Mutationen in die Antikörpergene einer reifenden B-Zelle bezeichnet. Es handelt sich um einen wichtigen Schritt des adaptiven Immunsystems. Mit Hilfe des Enzyms Activation Induced Cytidine Deaminase (AID oder auch AICDA) entstehen zufällige Veränderungen der DNA. AID desaminiert Cytosin zu Uracil in einzelsträngiger DNA. Das Enzym UNG entfernt Uracil und schafft eine abasische Stelle. Dort wir…
