cytosine in single-stranded DNA + H2O | Mus musculus | in response to antigens, B cells undergo two types of genomic alterations to increase antibody diversity. Affinity for antigen can be increased by introduction of point mutations into immunoglobulin heavy (IgH) and immunoglobulin light (IgL) variable regions by somatic hypermutation. Antibody effector functions can be altered by changing the expressed IgH constant region exons through IgH class switch recombination (CSR). Somatic hypermutation and CSR both require the B-cell-specific activation-induced cytidine deaminase protein (AID), which initiates these reactions through its single-stranded DNA-specific cytidine deaminase activity | uracil in single-stranded DNA + NH3 | - |

phosphoprotein | protein kinase A phosphorylates the Ser38. This phosphorylation event activates the enzyme to enable interaction with replication protein A, thereby augmenting the ability of activation-induced cytidine deaminase to effect class switch recombination in vivo | Mus musculus |
