c‐Rel–dependent Chk2 signaling regulates the DNA damage response limiting hepatocarcinogenesis
In response to genotoxic injury, c‐Rel upregulates ATM‐Chk2‐p53 pathway DNA damage proteins to limiting hepatocarcinogenesis. Abstract Background and Aims Hepatocellular carcinoma (HCC) is a leading cause of cancer‐related death. The NF‐κB transcription factor family subunit c‐Rel is typically protumorigenic; however, it has recently been reported as a

The dif/Xer recombination systems in proteobacteria. [PDF]
In E. coli, 10 to 15% of growing bacteria produce dimeric chromosomes during DNA replication. These dimers are resolved by XerC and XerD, two tyrosine recombinases that target the 28-nucleotide motif (dif) associated with the chromosome's replication ...

Study of VIPER and TATE in kinetoplastids and the evolution of tyrosine recombinase retrotransposons [PDF]
Kinetoplastids are a flagellated group of protists, including some parasites, such as Trypanosoma and Leishmania species, that can cause diseases in humans and other animals. The genomes of these species enclose a fraction of retrotransposons including VIPER and TATE, two poorly studied transposable elements that encode a tyrosine recombinase (YR) and ...

Challenging a Paradigm: the Role of DNA Homology in Tyrosine Recombinase Reactions [PDF]
SUMMARYA classical feature of the tyrosine recombinase family of proteins catalyzing site-specific recombination, as exemplified by the phage lambda integrase and the Cre and Flp recombinases, is the ability to recombine substrates sharing very limited DNA sequence identity.

Tyrosine recombinases are conserved in the three kingdoms of life. Here we present the first crystal structure of a full-length archaeal tyrosine recombinase, XerA from Pyrococcus abyssi, at 3.0 Å resolution.

Self‐control in DNA site‐specific recombination mediated by the tyrosine recombinase TnpI [PDF]
SummaryTn4430is a distinctive transposon of the Tn3family that encodes a tyrosine recombinase (TnpI) to resolve replicative transposition intermediates. The internal resolution site of Tn4430(IRS, 116 bp) contains two inverted repeats (IR1 and IR2) at the crossover core site, and two additional TnpI binding motifs (DR1 and DR2) adjacent to the core ...

Uropathogenic Escherichia coli (UPEC) is the most common etiologic agent of uncomplicated urinary tract infection (UTI). An important mechanism of gene regulation in UPEC is phase variation that involves inversion of a promoter-containing DNA element via

Evidence for a Xer/dif system for chromosome resolution in archaea. [PDF]
Homologous recombination events between circular chromosomes, occurring during or after replication, can generate dimers that need to be converted to monomers prior to their segregation at cell division.

Promoter Orientation of Prokaryotic Phase-variable Genes by PCR
One major mechanism of phase variable gene expression in prokaryotes is through inversion of the promoter element for a gene or operon. This protocol describes how to detect the promoter orientation of a phase-variable gene by PCR.
