Abstract excerpt
For 30 years two general mechanisms have competed to explain somatic hypermutation of immunoglobulin (Ig) genes. The first, the DNA-based model, is focused only on DNA substrates. The modern form is the Neuberger "DNA Deamination Model" based on activation-induced cytidine deaminase (AID) and short-patch error-prone DNA repair by DNA Polymerase-η operating around AID C-to-U lesions. The other is an RNA-based...
