A new function of AID, a crucial enzyme for the immune response has been uncovered by researchers. The discovery helps explain a rare genetic disorder that causes an immunodeficiency syndrome. AID initiates a mechanism whereby a break occurs in the DNA, within the antibody genes, and a segment is removed. The free ends on either side of the removed fragment must be rejoined to repair the DNA strand and, thus, produce a new class of antibody.
