A3F

A3F is an acronym that may refer to several distinct concepts across different domains. There is no single universally recognized meaning for A3F; the intended reference depends on context, discipline, and region. In biology and medicine, A3F most commonly denotes APOBEC3F, a member of the APOBEC3 family of cytidine deaminases. APOBEC3F contributes to innate immunity by deaminating cytosine to uracil in single-stranded DNA, a mechanism that can inactivate certain viruses. It has also been implicated in somatic mutagenesis in cancer and other genomic processes.

In technology and computing, A3F can appear as a project code, model designation, or internal shorthand used by companies or research groups. It may also function as a concise label within documentation or product catalogs, independent of any biological meaning. Other uses may include organization or program acronyms or catalog identifiers across various industries.

Disambiguation guidance: To determine the intended meaning, examine surrounding terms, the field of discussion, and any explicit references to biology, computing, or other domains. Checking authoritative glossaries, gene-symbol databases, or product catalogs can confirm whether A3F refers to APOBEC3F or to a technical code. If possible, provide additional context such as field, country, or related terms to refine the identification.
