Please edit the following with your excellent grammatical and, of course, medical knowledge:
G-protein-coupled receptor (GPCR) is a kind of receptor with 7-time-transmembrane structure. They extensively take part in the proliferation, differentiation ad transference of cells, especially in the regulation of a variety of physiological activities. The history of past decades has told us that 70% drugs in total developed worldwide are aimed at GPCR as a target. Therefore, GPCR is an eye catcher for medication. According to statistics, the proteins that belong to GPCR catalogue account for 30% of all animal proteins in total. Well, if the proteins of the GPCR catalogue are so important, I don't know how many people have dedicated to the work about them. Let's come and discuss it here, guys.

Well, the proteins of the GPCR catalogue may be important, but I don't think many researchers have dedicated themselves to studying them. Let's come and discuss it here, guys.

Thank you Mister Micawber. But I don't understand why you have deleted the sentence "Therefore, GPCR is an eye catcher for medication." IMO, it seems quite not bad as a sentence there to emphasize the importance of GPCR for medication (drug therapy).
wassup scientist?

looks like you want to use some ones findings in your article and you dont want to cut and paste his sentences..and thats why you need editing?? smart chap

best wishes on your publishing stint.
