Collaborative Team Advances the Understanding of an Important Activity Inside Cells
MSKCC Center News
A collaborative team of researchers from Memorial Sloan Kettering has determined the mechanism for a biological process that plays a key role in regulating cellular behavior. The process — and the enzymes that control it — has been studied for 30 years, but until now it was a mystery to researchers in the field how this complex reaction takes place. [Full text]
