This article is mentioned in:. Population, Han Chinese. Molecular Medicine Reports, 12, The organisms in which each group is found are indicated below the clade label. November Volume 12 Issue 5. DNA Repair Amst. In another study, Henry et al 17 compared the HBV editing by all seven enzymes in a quail cell line, which did not produce any endogenous DNA cytidine deaminase activity. J Gen Virol. Onset of liver disease results in changes to the levels of these deaminases. The rapid expansion of the A3 locus in humans indicates an important role in the host genome defense against exogenous viruses and endogenous retroelements 12 —
The AID/APOBEC family of nucleic acid mutators Genome Biology Full Text
The other ten members of the APOBEC family have not been fully The review begins with Apolipoprotein B Editing Catalytic subunit 1 (APOBEC1 or A1). Why AID expressed in germinal centers normally only targets. The AID/APOBEC family enzymes convert cytosines in APOBEC3F, APOBEC3G and APOBEC3H) and APOBEC4 In this review we will principally on the protein surface near the catalytic center for nucleic acid binding. Author summary The APOBEC family of cytidine deaminases are important AID is expressed primarily in germinal center B cells as part of the.
Population, Han Chinese.
Figure 1. Virol J. A2 is widely expressed in muscle; predominantly in cardiac and skeletal muscle, thus, is exclusively associated with the development of cardiac and skeletal muscle, as well as early embryogenesis 931 — Transgenic mice overexpressing APOBEC1 and AID develop tumors [ 9697 ], and the mutational context of C to T changes in genes commonly mutated in cancer is consistent with the action of these deaminases [ 24 ].

This mutagenic activity leads to somatic hypermutation SHM and class switch recombination Aberrant A2 expression resulted in nucleotide alterations in the transcripts of a specific target gene and may be involved in the development of human HCC via hepatic inflammation All of the TM and one TR had liver dysplasia.
are growing in germinal centers of secondary lymphoid or. 1Center for Immunology and Microbial Infections, Faculty of Medicine.
Here, we will review the cellular functions of AID/APOBEC family. Protein family review; Open Access; Published: 17 June . member of the RNA-editing deaminase family in germinal center B cells.
A3B gene deletion homozygosity was associated with mild liver fibrosis.

B, Hypermutation studies Study ref. J Mol Biol. In at least six distinct types of cancer, similar results have revealed that A3B is upregulated, and its preferred target sequence was frequently mutated and clustered
Evolutionary effects of the AID/APOBEC family of mutagenic enzymes on.

The ancestral enzyme in the family, AID, is expressed in germinal center B cells . While this article was under review, a new study was published. In this paper, I will review our current understanding of one protein family, the The APOBEC3 protein family was so named because all APOBEC3 proteins and Microbiology, BoxDuke University Medical Center, Durham, NC.
Whereas the function of AID is exerted in the nucleus, AID is predominantly cytoplasmic owing to the presence of a nuclear export signal NES at the extreme carboxyl terminus [ 42 — 44 ].

Ezzikouri et al A1 was markedly expressed in one sample although normalization of the expression levels was not conductedA2 transcripts were detected in certain samples, but A4 was not detected in any sample. View Article : Google Scholar.
Virus Res. Its packaging into virions is mediated by both viral and cellular RNAs [ 67 — 72 ], although the HIV Gag protein increases packaging efficiency [ 707273 ].

|The hepatitis B virus HBV infection is a prevalent type of infectious disease that is causing a global concern for public health 1.
Further members were identified as DNA mutators. Mol Cell.
Furthermore, expression of AID is needed in order to develop germinal-center-derived lymphomas in cancer-prone mice [ ], and its aberrant expression might also have a role in the development of cancer see for example [ ].
World J Gastroenterol. Recent analyses of the mutations have implicated APOBEC cytidine deaminases as significant factors in the mutagenesis of human cancer genomes 89 Furthermore, hyperediting of the novel A1 target no 1 mRNA that encoded a tumor suppressor gene, created stop codons and truncated protein products, which are linked to liver cancer
