Research reveals - the young protein can let the ribonucleic acid represent vigor
Organize the network for October 14 (Beijing time) according to the American physicist The report, the scientific research of the state university of Yale University and Wayne reveals, a kind of complicated RNA (ribonucleic acid) Act on protein together, can be had a facelift with the help of protein, mould into an appropriate shape again. These old RNAs existing for a long time, through evolving constantly, looks for the appropriate partner in young protein, finish the function mission by oneself auxiliarily. This research is published on the Nature network edition of October 13. The scientist once thought, most cellular activities were controlled by protein, but the finding in recent years, many kinds of RNA molecules play an important role in a large number of living beings move about. What this research is directed against is a kind of bigger with catalysis special RNA, that is to say that includes the son (group�� introns) in present known group ��. ��Include the son and come from growing in the group in living beings, fungi, alga, cell device of the plant and bacterium and ancient bacterium's genome originally, oneself montages the function, include the editing of the something small and hard to reflect in a lot of groups �� that need to be assisted by protein and could be finished. Study the relation between mechanism, shape and function that the thesis has recommended including the son in group ��, and point out it while help to include the son in group �� and other RNA form the best model, yeast protein Mss116 has played an important role. One of the thesis authors, researcher Ana and Mary of Howard medical research institute of Hughes send and teach and say, it is very interesting that the ones that include in this kind of group �� between sub RNA and Mss116 protein react each other: One pre-existing old the intersection of RNA and member, wait to be in the hope of meeting suitable its protein partner through a long one, it is evolving gradually too, makes and can follow " modernist " by oneself while this waits for Young for protein cooperation,thus not last oneself active course. The early textbook thinks RNA is only a kind of simple chemical media, in DNA (DNA) Serve as the messenger between order and protein synthesis. But in 3 billion human genetic codes, only 2% are the protein synthesis gene, but varied RNA is hiding the recombination, activation or secret closed of other most genes. Sent and said, understood the folding course of RNA was very crucial, it was very helpful for us to grasp the infection course of the virus of those only one RNA chromosome, such as C -type hepatitis or west Nile virus. In organism, function of RNA far than importance that is think before the 5 year such as we, need further studying their structure and function mechanism. (reporter Chang LiJun)
