This domain has been hypothesized to provide the enzymatic activity needed to convert C to U because it carries motifs characteristic
of cytidine deaminases.

As these cells rapidly proliferate, they also express high levels
of an enzyme known as activation - induced
cytidine deaminase (AID), which induces mutations in their DNA.
Predominant role for activation - induced
cytidine deaminase in generating IgG anti-nucleosomal antibodies
of murine SLE.
Liu and coworkers developed last year's base editor by combining three proteins: a
cytidine deaminase, a natural enzyme that converts C to uridine (U); a mutated Cas9 CRISPR enzyme that doesn't cut DNA but uses an associated guide RNA to target specific DNA sequences; and a protein that prevents reversion
of U back to C.
Dr. Honjo is well known for his discovery
of activation - induced
cytidine deaminase that is essential for class switch recombination and somatic hypermutation.
Global demethylation requires activation - induced
cytidine deaminase (AID)- mediated downregulation
of UHRF1 protein, and abolishing demethylation leaves thousands
of hypermethylated regions in the iPSC genome.
