In vitro Assay for Cytidine Deaminase Activity of APOBEC3 Protein

open access: yesBio-Protocol, 2014
Cytidine deaminases are enzymes that catalyze the removal of an amino group from cytidine, forming uridine. APOBEC3 (ApolipoproteinB mRNA editing enzyme, catalytic polypeptide like) proteins are cytidine deaminases that deaminate cytidines in ...

Multiple gene substitution by Target-AID base-editing technology in tomato

open access: yesScientific Reports, 2020
The use of Target activation-induced cytidine deaminase (Target-AID) base-editing technology with the CRISPR-Cas 9 system fused with activation-induced cytidine deaminase (AID) resulted in the substitution of a cytidine with a thymine.

Adenosine to inosine editing by ADAR2 requires formation of a ternary complex on the GluR-B R/G site [PDF]

open access: yes, 2002
RNA editing by members of the ADAR (adenosine deaminase that acts on RNA) enzyme family involves hydrolytic deamination of adenosine to inosine within the context of a double-stranded pre-mRNA substrate.

The antilymphocytic activity of brequinar sodium and its potentiation by cytidine: Effects on lymphocyte proliferation and cytokine production [PDF]

open access: yes, 1993
Based on its capacity to inhibit de novo pyrimidine biosynthesis by blocking dihydroorotate dehydrogenase activity, the antitumor agent brequinar sodium (BQR) has emerged as a new immunosuppressive agent.

Cytidine deaminases: AIDing DNA demethylation? [PDF]

open access: yesGenes & Development, 2010
The presence of 5-methylcytosine (5-mC) in DNA is a vital epigenetic mark in vertebrates. While the enzymes responsible for methylating DNA in vertebrates have been identified, the means by which this mark can be removed are still unclear. Recently, it has been shown that activation-induced cytidine deaminase (AID) contributes to the demethylation of ...

Mutant loxP vectors for selectable marker recycle and conditional knock-outs [PDF]

open access: yes, 2001
BACKGROUND: Gene disruption by targeted integration of transfected constructs becomes increasingly popular for studies of gene function. The chicken B cell line DT40 has been widely used as a model for gene knock-outs due to its high targeted integration

Characterization of Ovine A3Z1 Restriction Properties against Small Ruminant Lentiviruses (SRLVs) [PDF]

open access: yes, 2017
Intrinsic factors of the innate immune system include the apolipoprotein B editing enzyme catalytic polypeptide-like 3 (APOBEC3) protein family. APOBEC3 inhibits replication of different virus families by cytosine deamination of viral DNA and a not fully

Introduction of pathogenic mutations into the mouse Psen1 gene by Base Editor and Target-AID

open access: yesNature Communications, 2018
CRISPR-guided cytidine deaminases, including BE3 (Base Editor 3) and Target-AID (activation-induced cytidine deaminase), can covert C:G base pairs to T:A at target site.

Genotoxic stress and viral infection induce transient expression of APOBEC3A and pro-inflammatory genes through two distinct pathways

open access: yesNature Communications, 2021
The cytidine deaminase APOBEC3A is a main source of mutagenesis in many types of cancer. Here the authors reveal that transient up-regulation of APOBEC3A and other pro-inflammatory genes can occur due to viral infection and genotoxic stress via multiple ...
