WebbSpecifically, APOBEC3A is a cytidine deaminase enzyme that edits RNA transcripts of hundreds of cellular genes upon stimulation of innate immune cells by low oxygen tension (hypoxia) or antiviral factor interferon. Atpenin A5 induces APOBEC3A-mediated RNA editing in normoxia to levels comparable to those seen in hypoxia. Webb10 apr. 2024 · 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 …
