Trio of papers describe in unprecedented detail a major molecular target for drugs Three international teams of scientists, led by researchers at the University of California San Diego, University of Michigan and Stanford University, have published a trio of papers describing in unprecedented detail the structure and workings of G protein-coupled receptors (GPCRs), a large family of human proteins that are the target of one-third to one-half of modern drugs. Two of the papers are...

G protein-coupled receptors (GPCRs) are popular drug targets, accounting for about one-third of approved drugs and many hundreds of drugs currently in development. They act as molecular switches that transduce extracellular signals by activating heterotrimeric G proteins (G proteins) located at the inside of the cell. Changes in shape of these proteins determine essential processes, including whether an eye detects light, a virus invades a cell or a drug slows a racing heart. GPCRs sit in the...

PORTLAND, Ore. -- A pulsing heart cell is giving Oregon Health & Science University researchers insight into how it sends and receives signals, and that's providing clues into how heart disease and other disorders develop. In a study appearing in today's edition of Nature, John Scott, Ph.D., a Howard Hughes Medical Institute investigator and senior scientist at OHSU's Vollum Institute, found that heart muscle cells become enlarged when an intricate intracellular signaling pathway...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
