Cells carry their own growth switches. When enough nutrients—amino acids in particular—are available, cells flip this switch ...
UNC researchers discovered how a key step in cell signaling works by showing exactly how G proteins detach from receptors that many common medicines target. Scientists at the University of North ...
Illustration of small molecule modulation of β-arrestins and GPCR signaling pathways based on concepts developed by the Lefkowitz Laboratory, Duke University. To function normally, nearly every cell ...
