So after seeing
this article on the front page it dawned on me that a lot of people probably know ABOUT Folding@home. But how many people know what it actually DOES? You know, besides displaying a bunch of bars, numbers and colored balls attached together with sticks.
Don't worry, like the title says, this will be jargon free.
Many diseases are caused by proteins that are malfunctioning and most drugs work by interacting with said proteins to inhibit their activity. The way most drugs do this is by being designed to fit onto a protein and so the question becomes: what shape is that protein? If we know the shape then we can make a drug that fits onto that shape and hopefully we get a cure. Now with our technology today, and this is part of what I do, can be used to determine what the amino acid sequence of a protein is. Amino acids are the basic building blocks of proteins, there are twenty of them, and they link together in a straight chain. Kind of like a bunch of sausage links. Once we have that sequence we need to figure out how that chain is going to fold in on itself to become a functional protein. And here's where we have a problem. There are almost a limitless number of possibilities and there are a whole bunch of variables to consider depending on what the amino acid sequence is. So this is where folding@home comes in. In order to go through all of those possible folds, and figure out which ones may be correct, a whole ass-load of processing power is needed. Power that costs a lot of money and is too expensive most labs. So instead those clever scientists decided to use you! All those linked processors working together are a cheap, and very effective, alternative to buying a whole bunch of computers to do the work.
So the bottom line is that Folding@home allows us to find out protein structures that can then be used by pharmacologists to develop new drugs far cheaper and faster than could be done otherwise. So keep those consoles and PCs running guys and gals. You may be working on the protein that saves some lives.
I would really appreciate any comments on how accessible this was. Since I work in the field I'm not always aware of when I'm drowning people in concepts and jargon instead of useful information.

SPARTACUS APPRECIATES THIS POST
Thank you for explaining this TG, I admit when I saw this on the front page I was like....ummm...What's Folding@Home DO though.
This is awesome as hell, now I REALLY gotta get a PS3
Folding@Home: Think of the sausage links!!!!
I’ve folded over 770 “work units” (proteins) since I downloaded the client on March 22, 2007. W00t! And thanks for the explanation, even though I didn’t need it (I’m a science guy).
Thanks for clearing that up for us. I'm a blogger, not a rocket scientist. :-)
Hooray for simplifying complex terms!
How do you reconcile saying that folding@home benefits everyone with the fact that any product discovered or developed will be the intellectual property of one company to profit off of as they see fit? Is there some sort of stipulation on the use of folding@home on research that demands results are part of the public domain? I am a cynic by nature, and although I do trust technology I don't trust corporations. What I mean to say is let's just say PS3's find the cure for cancer, who gets that cure? Phizer? When they sell that cure for a huge profit (to fund future research and yachts) would anything get kicked back to the little people who made it possible? Cures for the big diseases attacked by f@h would be profitable enough to pay for every PS3 in the f@h network.
that's some interesting shit.

I thought folding at home was helping research at Stanford. that's doesn't seem so bad.
@Resting
Whoa there big fella, keep in mind what's actually happening here. All that Folding@home does is solve structures, that information is then put into databases that are accessuble to anyone (such as the PDB). What you're talking about has to do with who uses that information and for what purpose. Yes drug companies do use the info, but, as ceark pointed out, so do researchers at various Universities etc. Also the fact that drug companies use these results to help develop new drugs is not a bad thing. Like it or not, the majority of advances in the pharmacological field are made by companies like Phizer and to stimulate research they need to make a profit. Now I'm not trying to start a discussion about how drug prices are set and whether it's moral or anything like that. That would just get insane :P. If you're REALLY curious, feel free to check out any basic health care economics book and flip to the drug chapter. You may be surprised ;).
The more you know... :D
I remember reading a book by Isaac Asimov about extremely large numbers, and not to be a pessimist, but this was the situation regarding protein folding:
The number of possible protein folds was something like 10^527. Let's assume that the universe is a cube, 10 billion light years on each side, and that the universe is filled with computers the size of neutrinos, each capable of turning out a billion answers per second. If you ran all of them for 300 million years, the odds of one of those possible results being correct was like 1 in 10^410...not saying that this is necessarily a bad idea, just that...it's not going to do much, unfortunately. :(
He'd be absolutely right if it was totally random. We can glean information from various techniques to narrow down the possible folds, but I hear ya. Folding@Home may not lead to anything productive but that goes for most things in the world of science. You just take your best shot. The alternative is not doing it at all, in which case the chances of success are even worse ;)
