Farnesoid X receptor regulates cystathionase

... FXR in the regulation of CSE transcription. The molecular mechanism of the CSE activation by FXR was revealed by identifying a sequence in the 5' flanking region of CSE gene containing a potential IR1 binding site. Co-transfection of HepG2 cells with luciferase reporter vector containing four copies of ...

Scientists reveal structure of new botulism nerve toxin subtype

... The current study of botulinum subtype E, also conducted at the NSLS, disproved that assumption, taking the scientists by surprise. Instead of the flanking arrangement, the binding and protein-cleaving domains of subtype E are both on the same side of the translocation domain. In addition, while all ...

200,000 rice mutants available worldwide for scientific investigation

... somewhere between 180,698 and 460,000. Two hundred thousand rice mutants are now available and have been mapped by the insertion of what are known as flanking sequence tags small pieces of DNA or molecular tags that integrate into the rice genome. This approach is useful because it allows scientists to ...

Pitt researchers describe molecular '2-step' leading to protein clumps of Huntington's disease

... details of how the aggregation behavior of huntingtin depends, in a surprisingly intricate way, on the neighboring segments of amino acid sequence flanking the polyglutamine. They found that longer polyglutamine sequences have the ability to disrupt the structure of a neighboring region, 17 amino ...

CSHL scientists clarify editing error underlying genetic neurodegenerative disease

... exons -- are pasted together, forming a mature messenger RNA transcript. In an unedited RNA molecule, the boundaries between an intron and its two flanking exons are called splice sites. Such sites are composed of short sequences of RNA "letters" (called "bases"), which are referred to by single-letter ...

Tracking poultry litter phosphorus: Threat of accumulation?

... MADISON, WI, JANUARY 26, 2009 The Delmarva Peninsula, flanking the eastern shore of the Chesapeake Bay, is home to some 600 million chickens. The resulting poultry manure and some of the chicken house bedding ...

Stowers Institute's Baumann Lab identifies key step in maturation pathway of telomerase

... "It was highly unexpected that the spliceosome could have such a function, as the two steps of removing an internal piece of RNA and gluing the flanking ends together are tightly coupled during intron removal. To our knowledge this is the first example where uncoupling of the first and second step of ...

MU scientists 'see' how HIV matures into an infection

... precursor, something that had not been accessible before using conventional techniques. The researchers discovered that the 'tail,' or the flanking amino acid residues, of the HIV-1 protease precursor go through a temporarily formed tunnel where the tail is cut off. At this point, the protease ...

A second career for a growth factor receptor: keeping nerve axons on target

... molecules that repel growing axons. In it, an immature neuron is placed on a microscopic running track, just as it starts to develop an axon. When flanking lanes are carpeted with repellant factors, the sprouting axon bursts from the block but remains in its lane like a well-coached runner, avoiding ...
