Mouse embryonic fibroblasts derived from Odin deficient mice display a hyperproliiferative phenotype. Odin is a recently identified cytosolic phosphotyrosine binding PTB domain containing negative regulatory protein, that was discovered on the basis of its ability to undergo tyrosine phosphorylation upon stimulation by epidermal growth Odin is a recently identified cytosolic phosphotyrosine binding PTB domain containing negative regulatory protein, that was discovered on the basis of its ability to undergo tyrosine phosphorylation upon stimulation by epidermal growth factor in HeLa cells.
The protein The 2 micron plasmid of Saccharomyces cerevisiae: A miniaturized selfish genome with optimized functional competence. The 2 micron plasmid of Saccharomyces cerevisiae is a relatively small multi-copy selfish DNA element that resides in the yeast nucleus at a copy number of per haploid cell. The plasmid is able to persist in host populations with The plasmid is able to persist in host populations with almost chromosome-like stability with the help of a partitioning system and a copy number control system.
The first part of this article describes the properties of the partitioning system comprising two plasmid coded proteins, Rep1 and Rep2, and a partitioning locus STB.
Current evidence supports a model in which the Rep-STB system couples plasmid segregation to chromosome segregation by promoting the physical association of plasmid molecules with chromosomes.
In the second part, the focus is on the Flp site-specific recombination system housed by the plasmid, which plays a critical role in maintaining steady state plasmid copy number. The Flp system corrects any decrease in plasmid population by promoting plasmid amplification via a recombination induced rolling circle replication mechanism.
The Flp system has been successfully utilized to understand mechanisms of site-specific recombination and to bring about directed genetic alterations for addressing fundamental problems in biology and for accomplishing bio-engineering objectives. A particularly interesting, and perhaps less well known and underappreciated, application of Flp in revealing unique DNA topologies required to confer functional competence to DNA-protein machines is discussed.
Single-molecule FRET unveils induced-fit mechanism for substrate selectivity in flap endonuclease 1. Yet, it is unclear how the Here, single-molecule sub-millisecond and millisecond analyses of FEN1 reveal a protein-DNA induced-fit mechanism that efficiently verifies substrate and suppresses off-target cleavage. FEN1 sculpts DNA with dna replication research papers kinetics to test DNA substrate, dna replication research papers.
Strikingly, FEN1 never misses cleavage of its cognate substrate while blocking probable formation of catalytically competent interactions with noncognate substrates and fostering their pre-incision dissociation. The MCM-associated protein MCM-BP is important for human nuclear morphology. Mini-chromosome maintenance complex-binding protein MCM-BP was discovered as a protein that is strongly associated with human MCM proteins, known to be crucial for DNA replication in providing DNA helicase activity.
The Xenopus MCM-BP The Xenopus MCM-BP homologue appears to play a role in unloading MCM complexes from chromatin after DNA synthesis; dna replication research papers, the importance of MCM-BP and its functional contribution to human cells has been unclear. Here we show that depletion of MCM-BP by sustained expression of short hairpin RNA shRNA results in highly abnormal nuclear morphology and centrosome amplification.
The abnormal nuclear morphology was not seen with depletion of other MCM proteins and was rescued with shRNA-resistant MCM-BP. MCM-BP depletion was also found to result in dna replication research papers activation of the G2 checkpoint, slowed progression through G2 and increased replication protein A foci, indicative of replication stress.
In addition, MCM-BP depletion led to increased cellular levels of MCM protein Functional role for c-myc in mitogenic response to platelet-derived dna replication research papers factor, dna replication research papers. Using mouse mammary tumour virus promoter: c-myc recombinant plasmids, 3T3 sublines were constructed in which hydrocortisone was the Using mouse mammary tumour virus promoter: c-myc recombinant plasmids, dna replication research papers, 3T3 sublines were constructed in which hydrocortisone was the primary determinant of myc mRNA Mismatch Repair Processing of Carcinogen-DNA Adducts Triggers Apoptosis.
The DNA mismatch repair pathway is well known for its role in correcting dna replication research papers errors of DNA replication. We report here a novel role for mismatch repair in signaling programmed cell death in response to DNA damage induced by We report here a novel role for mismatch repair in signaling programmed cell dna replication research papers in response to DNA damage induced by chemical carcinogens.
Cells proficient in Regulation of extracellular matrix metabolism by growth factors in human skin fibroblasts. Interferon and sodium butyrate inhibit the stimulation of poly ADP-ribose synthetase in mouse cells stimulated to divide.
The activity of poly ADP-ribose synthetase, a chromatin-bound enzyme, increases when quiescent 3T3 cells are stimulated to proliferate.
The elevation of enzymatic activity requires de novo RNA and protein synthesis. Interferon IFN or Interferon IFN or sodium butyrate, when added to quiescent cells at the time of stimulation, suppressed the rise of enzymatic activity as well as initiation of DNA synthesis in cells. However, other DNA synthesis inhibitors like methotrexate, dna replication research papers, FudR and hydroxyurea had little effect on the elevation of poly ADP-ribose synthetase in quiescent cells.
Sequence-specific pausing during in vitro DNA replication on double-stranded Dna replication research papers templates. Sequence-specific pausing occurs during DNA synthesis catalyzed by the bacteriophage T4 DNA polymerase holoenzyme in the presence of the T4 helix destabilizing protein gene 32 protein. Two of the six strongest pause sites on a Two of the six strongest pause sites on a double-stranded bacteriophage fd DNA template dna replication research papers in regions where hairpin helices are predicted to form when the DNA is single stranded.
However, the other pause sites are in regions that are not obviously involved in secondary structure. At this resolution, a clustering of sites is observed, suggesting that the polymerase holoenzyme may become destabilized when moving along selected regions of the DNA and then pause at one or more of several closely spaced positions.
The addition of the T4 gene 41 protein a DNA helicase that forms part of the T4 primosome to the above replication system greatly increases the rate of fork movement and e Studies on DNA Replication in the Bacteriophage T4 a gif System.

Thymic lymphomas arising in Msh2 deficient mice display a large increase in mutation frequency and an altered mutational spectrum. In the current study, the mutation frequency and mutational spectrum in In the current study, the mutation frequency and mutational spectrum in thymic lymphoma arising in Msh2 deficient mice are investigated. The tumor mutational spectrum is characterized by an increase in base substitutions occurring at A:T sites, and multiple mutations, as well as a minor increase in -1 frameshifts.
We analyzed dna replication research papers in different parts of the tumors, and different regional hotspots could be identified. Several hotspot mutations that are a rare event in normal tissues were identified in the tumor tissu Related Topics.

Figure 1: DNA Replication Process. Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bidirectional from the origin. A number of proteins are associated with the replication fork which helps in terms of the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new DNA by adding complementary nucleotides to the Jun 26, · Research papers, journal articles and scientific articles related to DNA replication: Here you will find abstracts and references of the latest publications from journals in this sector The Cdc6 protein is an essential component of pre-replication complexes (preRCs), which assemble at origins of DNA replication during the G1 phase of the cell cycle.
