ABC3A Polyclonal Antibody from Bioassay Technology Laboratory

This gene is a member of the cytidine deaminase gene family. It is one of seven related genes or pseudogenes found in a cluster: thought to result from gene duplication: on chromosome 22. Members of the cluster encode proteins that are structurally and functionally related to the C to U RNA-editing cytidine deaminase APOBEC1. The protein encoded by this gene lacks the zinc binding activity of other family members. The protein plays a role in immunity: by restricting transmission of foreign DNA such as viruses. One mechanism of foreign DNA restriction is deamination of foreign double-stranded DNA cytidines to uridines: which leads to DNA degradation. However: other mechanisms are also thought to be involved: as anti-viral effect is not dependent on deaminase activity. Two transcript variants encoding different isoforms have been found for this gene
