Noninfectious retrovirus particles drive the APOBEC3/Rfv3 dependent neutralizing antibody response. [PDF]

, 2011
Members of the APOBEC3 family of deoxycytidine deaminases counteract a broad range of retroviruses in vitro through an indirect mechanism that requires virion incorporation and inhibition of reverse transcription and/or hypermutation of minus strand ...

Variable contexts and levels of hypermutation in HIV-1 proviral genomes recovered from primary peripheral blood mononuclear cells [PDF]

, 2008
APOBEC-mediated cytidine cleamination of HIV-1 genomes during reverse transcription has been shown to be a potent mechanism of host restriction for HIV-1 infection ex vivo and in vitro.

Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

Journal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...

Induction of homologous recombination between sequence repeats by the activation induced cytidine deaminase (AID) protein

eLife, 2014
The activation induced cytidine deaminase (AID) protein is known to initiate somatic hypermutation, gene conversion or switch recombination by cytidine deamination within the immunoglobulin loci.

Natural Variation of a PPR Coding Gene SST1 Confers Salt Tolerance During Soybean Domestication

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soil salinity is one of the constraints that adversely affect seedling growth and limit soybean yield. Identifying salt tolerance genes and profiling their allele variants are crucial for elucidating the mechanisms underlying salt tolerance in soybean and enabling the genetic improvement of salt‐tolerant cultivars.

SWISS: multiplexed orthogonal genome editing in plants with a Cas9 nickase and engineered CRISPR RNA scaffolds

Genome Biology, 2020
We describe here a CRISPR simultaneous and wide-editing induced by a single system (SWISS), in which RNA aptamers engineered in crRNA scaffold recruit their cognate binding proteins fused with cytidine deaminase and adenosine deaminase to Cas9 nickase ...

Artificial Mutations in the Nuclear Gene Encoding Mitochondrial RNA Polymerase Restore Pollen Fertility in Cytoplasmic Male Sterile Tomato

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cytoplasmic male sterility (CMS) and restorer of fertility (Rf) are important traits in F1 hybrid breeding. However, the CMS/Rf system has not been used in tomatoes because of the limited resources of Rf lines. In this study, we performed mutagenesis in tomato CMS seeds and successfully obtained 13 suppressor mutants with pollen fertility ...

Double-stranded DNA deaminase DddAE1347A can increase the efficiency and targeting range of cytidine base editors

Genome Biology
Background Cytidine base editors (CBEs) consist of a single-strand specific cytidine deaminase fused to Cas9 nickase, enabling efficient C-to-T conversion across diverse organisms.

Somatic hypermutation of IGVH genes and aberrant somatic hypermutation in follicular lymphoma without BCL-2 gene rearrangement and expression

Haematologica, 2008
Background Follicular lymphoma is characterized by the t(14;18) translocation resulting in constitutive expression of BCL-2 protein; however approximately 10–15% of follicular lymphomas do not express BCL-2 protein, and a small fraction of these cases ...

The nucleotidohydrolases DCTPP1 and dUTPase are involved in the cellular response to decitabine [PDF]

, 2016
Decitabine (5-aza-2acute;-deoxycytidine, aza-dCyd) is an anticancer drug used clinically for the treatment of myelodysplastic syndromes and acute myeloid leukemia that can act as a DNA-demethylating or genotoxic agent in a dose-dependent manner.
