APOBEC4

C->U-editing enzyme APOBEC-4, also known as Apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 4, is a is_associated_with::protein that in humans is encoded by the APOBEC4 is_associated_with::gene.

Function
This gene encodes a member of the AID / is_associated_with::APOBEC family of polynucleotide (deoxy)is_associated_with::cytidine deaminases, which convert is_associated_with::cytidine to is_associated_with::uridine. Other AID/APOBEC family members are involved in mRNA editing, somatic hypermutation and recombination of immunoglobulin genes, and innate immunity to retroviral infection.
