Key drug receptor: Atom-level simulation of a G protein-coupled receptor could lead to improved drug design
Roughly 40 percent of all medications act on cells’ G protein-coupled receptors (GPCRs). One of these receptors, beta 2 adrenergic receptor site (B2AR), naturally transforms between two base configurations; knowing the precise location of each of approximately 4,000 atoms is crucial for ensuring a snug fit between it and the drug. Now, researchers at Stanford and Google have conducted an unprecedented, atom-scale simulation of the receptor site’s transformation, a feat that could have significant impact on drug design. This is the first scientific project to be completed using Google Exacycle’s cloud computing platform, which allows scientists to crunch big data on Google’s servers during periods of low network demand…
