...enzyme reported today has a makeup which places it as a new member of a family of enzymes known as G protein-coupled receptor kinases, according to the report's au- thors. These kinases are responsible forturning off signal transduction, the cascade ofreactions involved in communication with othercells...
...ARGUMENTS FOR building the multibillion-dollar space station Freedom is that it would provide a zero-gravity laboratory to grow bigger and purer protein and silicon crystals. But increasingly there is a question as to whether the crystal-growing techniques, at least for proteins, are all that reliable. Reviewing a decade's worth of such space efforts, scientists writing in Nature found that less than a quarter of the experiments actually worked, and then with only mixed success. Their recommendation: rent time aboard the already orbiting Russian space station...
...Association journal. In a study of some 1,900 men ages 42 to 60, Finnish researchers determined that the risk of heart attack was greater among men with high blood levels of iron than in those with lower readings. For each 1% increase in the amount of ferritin (a protein that binds iron), the risk of heart attack increased by 4%. The reason, many doctors suspect, is that iron may interact with LDL, "the bad cholesterol," in a way that promotes the formation of plaque on arterial walls...
...carrying out their research, Gusella's grouputilized a relatively new technique invented byanother co-author, University of Wales geneticistAlan Buckler, which allows better identificationof those genes which actually translate into agiven protein, in this case alpha-adducin...
Sequences of DNA contain large segments, calledintrons, which are not actually translated intothe protein formed. This often makes finding thosegenes responsible for a given protein--the exonswhich lie between the introns--extremely difficultfor researchers, who must sift through as much as98 or 99 percent "junk...
