Summary: Enables cytidine deaminase activity. Acts upstream of or within cytidine to uridine editing and mRNA modification. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including head mesenchyme; lower urogenital tract; reproductive system; urethra epithelium; and vertebral axis musculature. Orthologous to human APOBEC2 (apolipoprotein B mRNA editing enzyme catalytic subunit 2). [provided by Alliance of Genome Resources, Dec 2024]

Data show that APOBEC2 is preferentially associated with slow-twitch muscle, with its abundance being considerably greater in soleus compared with gastrocnemius muscle and, within soleus muscle, in slow as opposed to fast muscle fibers.

both APOBEC2 (despite being an ancestral member of the family with no obvious redundancy in muscle) and APOBEC3 (despite its proposed role in restricting endogenous retrotransposition) are inessential for mouse development, survival, or fertility

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
