To overcome this limitation, we developed a CRISPR-Cpf1-based BE by fusing the rat cytosine deaminase APOBEC1 to a catalytically inactive version of Lachnospiraceae bacterium Cpf1.
Title: Base editing with a Cpf1-cytidine deaminase fusion.
Results show that expression of APOBEC1 induces a mutator phenotype in 2 different cellular models.
Title: The RNA editing enzyme APOBEC1 induces somatic mutations and a compatible mutational signature is present in esophageal adenocarcinomas.
Apobec-1 increased COX-2 expression and COX-2 mRNA stabilization in neurogenic cells, and failed to catalyze C-to-U editing of COX-2 mRNA
Title: Apobec-1 increases cyclooxygenase-2 and aggravates injury in oxygen-deprived neurogenic cells and middle cerebral artery occlusion rats.
It was found that rat APOBEC-1 overexpression had a hypermutation pattern similar to that of APOBEC-3s on its substrate apolipoprotein B mRNA.
Title: Hypermutation of ApoB mRNA by rat APOBEC-1 overexpression mimics APOBEC-3 hypermutation.
Taken together, these results demonstrate a model in which APOBEC1 induction during encephalitis in neurons may aid in thwarting HSV-1 infection.
Title: APOBEC1-mediated editing and attenuation of herpes simplex virus 1 DNA indicate that neurons have an antiviral role during herpes simplex encephalitis.
Editing by APOBEC-1 was studied in yeast using Gal4 linked to Gal80 via an apo B cassette (Gal4-C) or via a mouse Ig heavy chain gene variable region (Gal4-VH). APOBEC-1 induced C to U editing in ~15% of the Gal4-C transcripts, but did not affect Gal4-VH.
Title: The cytidine deaminases AID and APOBEC-1 exhibit distinct functional properties in a novel yeast selectable system.
observations allow speculation (i) that APOBEC-mediated C-to-U editing may contribute to the sequence variation of viruses that replicate entirely through RNA, and (ii) that additional cellular RNA substrates might exist for the APOBEC enzymes
Title: APOBEC-mediated editing of viral RNA.
may have roles in epigenetic reprogramming and cell plasticity

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.
