APOBEC3s: DNA‐editing human cytidine deaminases [PDF]
AbstractNucleic acid editing enzymes are essential components of the human immune system that lethally mutate viral pathogens and somatically mutate immunoglobulins. Among these enzymes are cytidine deaminases of the apolipoprotein B mRNA editing enzyme, catalytic polypeptide‐like (APOBEC) super family, each with unique target sequence specificity and ...

DNA editing in DNA/RNA hybrids by adenosine deaminases that act on RNA. [PDF]
Adenosine deaminases that act on RNA (ADARs) carry out adenosine (A) to inosine (I) editing reactions with a known requirement for duplex RNA. Here, we show that ADARs also react with DNA/RNA hybrid duplexes.

Rewriting Human History and Empowering Indigenous Communities with Genome Editing Tools. [PDF]
Appropriate empirical-based evidence and detailed theoretical considerations should be used for evolutionary explanations of phenotypic variation observed in the field of human population genetics (especially Indigenous populations). Investigators within

Isoenzymatic forms of human cytidine deaminase [PDF]
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 ...

Highly-potent, synthetic APOBEC3s restrict HIV-1 through deamination-independent mechanisms.
The APOBEC3 (A3) genes encode cytidine deaminase proteins with potent antiviral and anti-retroelement activity. This locus is characterized by duplication, recombination, and deletion events that gave rise to the seven A3s found in primates.

AID/APOBEC-like cytidine deaminases are ancient innate immune mediators in invertebrates
The AID/APOBEC cytidine deaminase family are nucleic acid editors, important for antigen receptor expression and thought to have evolved along with vertebrate adaptive immunity.

APOBEC3G & HTLV-1: Inhibition without deamination
APOBEC3G is a cellular cytidine deaminase that was recently identified as the Vif-sensitive antiviral host factor responsible for the restriction of vif-defective HIV-1 in primary human cells and certain non-permissive T cell lines.

Efficient deamination of 5-methylcytidine and 5-substituted cytidine residues in DNA by human APOBEC3A cytidine deaminase. [PDF]
Deamination of 5-methylcytidine (5MeC) in DNA results in a G:T mismatch unlike cytidine (C) deamination which gives rise to a G:U pair. Deamination of C was generally considered to arise spontaneously.
