Nobel chemistry prize winners known
Americans Robert Lefkowitz and Brian Kobilka won the 2012 Nobel Prize in chemistry Wednesday for studies of protein receptors that let body cells sense and respond to outside signals. Such studies are key for developing better drugs, News1130.com reports.
The Royal Swedish Academy of Sciences said the two researchers had made groundbreaking discoveries, mainly in the 1980s, on an important family of receptors, known as G-protein-coupled receptors.
About half of all medications act on these receptors, so learning about them will help scientists to come up with better drugs.
The human body has about 1,000 kinds of such receptors, structures on the surface of cells, which let the body respond to a wide variety of chemical signals, like adrenaline. Some receptors are in the nose, tongue and eyes, and let us sense smells, tastes and light.
Lefkowitz, 69, is an investigator at the Howard Hughes Medical Institute and professor at Duke University Medical Center in Durham, North Carolina.
Kobilka, 57, is a professor at Stanford University School of Medicine in California.
Lefkowitz said he was fast asleep when the Nobel committee called, but he didn't hear it because he was wearing ear plugs. So his wife picked up the phone.
"She said, 'There's a call here for you from Stockholm,'" Lefkowitz told The Associated Press. "I knew they ain't calling to find out what the weather is like in Durham today."
He said he didn't have an "inkling" that he was being considered for the Nobel Prize.
"Initially, I expected I'd have this huge burst of excitement. But I didn't. I was comfortably numb," Lefkowitz said.
Kobilka said he found out around 2:30 am, after the Nobel committee called his home twice. He said he didn't get to the phone the first time, but that when he picked up the second time, he spoke to five members of the committee.
"They passed the phone around and congratulated me," Kobilka told AP. I guess they do that so you actually believe them. When one person calls you, it can be a joke, but when five people with convincing Swedish accents call you, then it isn't a joke."
He said he would put his half of the 8 million kronor ($1.2 million) award toward retirement or "pass it on to my kids."
The academy said it was long a mystery how cells interact with their environment and adapt to new situations, such as when
adrenaline acts on cells to increase blood pressure and make the heart beat faster.
