The APOBEC3B cytidine deaminase is an adenovirus restriction factor. [PDF]
PLoS Pathog, 2023 Human adenoviruses (HAdVs) are a large family of DNA viruses counting more than a hundred strains divided into seven species (A to G). HAdVs induce respiratory tract infections, gastroenteritis and conjunctivitis. APOBEC3B is a cytidine deaminase that restricts several DNA viruses. APOBEC3B is also implicated in numerous cancers where it is responsible

CCCTC-binding factor locks premature IgH germline transcription and restrains class switch recombination [PDF]
, 2017 In response to antigenic stimulation B cells undergo class switch recombination (CSR) at the immunoglobulin heavy chain (IgH) to replace the primary IgM/IgD isotypes by IgG, IgE, or IgA.

Nature Communications, 2023 APOBEC’s are a family of cytidine deaminases that induce mutations in viruses to inhibit their replication and maintain cell integrity. Here, Manjunath et al show that APOBEC3B also inhibits viral replication by stimulating the innate immune sensor ...

Isoenzymatic forms of human cytidine deaminase [PDF]
Protein Engineering Design and Selection, 2005 Cytidine deaminase (CDA) purified from human placenta revealed the presence of five isoenzymatic forms that differ only in their isoelectric point. Since human cytidine deaminase exists in two variants (CDA 1 and CDA 2) with a non-conservative amino acid substitution at codon 27, in this work we demonstrate that these two variants may combine together ...

Precise base editing with CC context-specificity using engineered human APOBEC3G-nCas9 fusions
BMC Biology, 2020 Background Cytidine base editors (CBEs), composed of a cytidine deaminase fused to Cas9 nickase (nCas9), enable efficient C-to-T conversion in various organisms. However, current base editors can induce unwanted bystander C-to-T conversions when multiple

Cytidine Deaminase—A Marker for Pre-Eclampsia? [PDF]
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1985 Cytidine deaminase (cytidine aminohydrolase, EC 3.5.4.5) was measured in blood collected for routine antenatal monitoring from 590 unselected pregnant women. The enzyme measurements were made without prior knowledge of the clinical condition of the patients.

Programmable base editing of zebrafish genome using a modified CRISPR-Cas9 system. [PDF]
, 2017 Precise genetic modifications in model animals are essential for biomedical research. Here, we report a programmable "base editing" system to induce precise base conversion with high efficiency in zebrafish. Using cytidine deaminase fused to Cas9 nickase,

Single-stranded DNA binding proteins influence APOBEC3A substrate preference
Scientific Reports, 2021 The cytidine deaminase, APOBEC3A (A3A), is a prominent source of mutations in multiple cancer types. These APOBEC-signature mutations are non-uniformly distributed across cancer genomes, associating with single-stranded (ss) DNA formed during DNA ...
