An HIV Protein Plays a Surprising Role in Gene Activation

..., where it binds to region rich in thymine (T) and adenine (A) named the TATA box. The first transcription factor to associate with the TATA box is called TFIID, a large protein complex containing a protein that binds the TATA box (aptly named the TATA-box-binding protein, or TBP) and several cofactors calle...

Second messenger NAADP shows fast, dose-related impact on satiety cycle

...ntroversial natural molecule called nicotinic acid adenine dinucleotide phosphate (NAADP), which is active in cells from plants to humans. NAADP is thought to be a so-called "second messenger," because it works from inside cells, rather than externally. However its mode operation remains unknown ?and controv...

Scientists take aim at virulent bacteria by decoding machinery of key control enzyme

...nown for many years that an enzyme called Dam (DNA adenine methyltransferase) plays a role in regulating gene expression in many bacteria. Each time the bacteria reproduce, Dam modifies the A (adenine) nucleotide in the DNA sequence GATC through a chemical reaction known as methylation. Methylation is a biol...

Study finds 60 new genes controlled by DNA snippet

...NA chains may contain any one of four nucleobases: adenine (A), thymine (T), guanine (G) and cytosine (C). Any sequence of code starting with 2 Cs, followed by any combination of 6 As or Ts, and ending in 2 Gs is a CArG box. According to Miano, there are 1,216 variations of CArG box that together occur appr...

Precision biochemistry tracks DNA damage in fish

... the researchers to identify and measure damage to adenine and guanine, specific chemical components or bases of DNA, at extraordinarily low levels--five lesions out of a 100 million bases in one case. The results correlated well with earlier research and revealed similar damage to liver DNA (more likely tie...
