Protein
Single-stranded DNA cytosine deaminase
Gene
Aicda, Aid
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Single-stranded DNA-specific cytidine deaminase. Involved in somatic hypermutation, gene conversion, and class-switch recombination in B-lymphocytes. Required for several crucial steps of B-cell terminal differentiation necessary for efficient antibody responses. May also play a role in the epigenetic regulation of gene expression by participating in DNA demethylation.1 Publication

Catalytic activityi

Cytosine in single-stranded DNA + H2O = uracil in single-stranded DNA + NH3.

Cofactori

Zinc By similarity.
