Long-sought protein structure may help reveal how 'gene switch' works

...ek, the NIST/BNL team reports that it has definedfor the first timethe structure of a "metabolic switch" found inside most types of bacteriathe cyclic amp (cAMP) receptor protein, or CRPin its "off" state. CRP is the "binding site" (attachment point) for cAMP, a small molecule that, once attached, serves...

Gene's newly explained effect on height may change tumor disorder treatment

...ology, and director of Washington University Neurofibromatosis Center. "However, those mice were normal." NF1 also increases brain levels of cyclic amp (cAMP), an important signaling molecule. Working with the same line of mice where stem cells in the brain do not make the NF1 protein, researchers fed...

For some who have lost their sense of smell, a once popular asthma drug could help

...l function were evaluated regularly throughout the study. The researchers had previously discovered that decreased levels of two proteins V cyclic amp (cAMP) and cyclic GMP (cGMP) -- in nasal mucus inhibited growth and development of olfactory receptor cells and thus caused smell loss. For this reaso...

Green alga genome project catalogs carbon capture machinery

...es have lost facets of these capabilities. "Yet Chlamy possesses the largest known array of enzymes that manufacture the signaling molecules cyclic amp and cyclic GMP. These cyclic nucleotides play key roles in shuttling nutrients into the cell, controlling motility of the organism via flagellar funct...

Natural antibiotics yield secrets to atom-level imaging technique

...mbs," Ramamoorthy said. "We'd like to exploit their properties to design super-smart bombs, but before we can do that, we need to understand how these amp smart bombs interact with membranes to destroy bacteria. We need to know how they're shaped before, during and after the process of attaching to bacte...

Scientists unravel clue in cortisol production

...ccur after the adrenal gland receives the signal. One of the things the signal does is cause adrenal cells to increase their production of cyclic amp (cAMP), a chemical that encourages proteins to interact. So they began by causing the cells to make more cAMP. Then as the proteins assembled on the D...

Lack of key enzyme associated with development of rare tumor

...se function as "second messengers," often stimulating the cell to begin an activity. In the case of adrenal cells, cyclic nucleotides, such as cyclic amp and cyclic GMP, may stimulate cell growth or other activities. Once the activity has ended, phosphodiesterases degrade the cyclic nucleotides, thereb...

EGF receptor activation prevents microbes from going more than skin deep

...sen and colleagues from Lund University, Sweden, investigated what triggers amp production in human skin. Interestingly, they found that AMPs were produced...rigger for the immune response in skin. The authors went on to show that amp was produced through activation of the epidermal growth factor receptor (EG...

Darkness unveils vital metabolic fuel switch between sugar and fat

...lecular cousins ?adenosine triphosphate (ATP), adenosine diphosphate (ADP), both vital to providing energy to cells, and the signaling molecule cyclic amp -- did not produce the same effect. The mice injected with 5'-AMP also were found to have a lower body temperature, a sign of torpor. Core body te...

Environmental chemical cocktail may sabotage sperm

...l oestrogens was still not clear, but the researchers discovered that both genistein and nonylphenol significantly stimulated the production of cyclic amp ?a chemical messenger, produced within the cell after external compounds have acted on the cell, that prompts an appropriate response. In the case of ...

Newly discovered genetic disease sheds light on body's water balance

...en though vasopressin was absent, Feldman developed an assay for receptor activity. One marker of this activity is an increase in the amount of cyclic amp (cAMP) within the cell. He worked in the laboratory of pediatric endocrinologist Walter Miller, MD, using a method to determine cAMP levels in cells b...
