Protein folding
« on: 03/12/2005 11:23:44 »
I'm taking part in the Stamford University project called Folding@home. Spare processor time on my PC is utilised to do calculations and the results are sent back to the uni.
I know the calculations are to do with protein folding, but that's all I know & I haven't been able to glean any additional info. Does anyone know exactly what the calculations are doing & why this is important to cancer research?

The goal may be to predict a potential 3D conformation (tertiary structure) of a protein, out of it`s aminoacid sequence. Or it is possible that calculations are about a sequence of events that will finaly lead to it`s stable conformation, including interactions with other proteins, eg. chaperones. Actually, it`s imposible to tell from here :(

Anyway, it is belived that protein folding has a role in cancer development. One idea is that mutations whitch confer a protein with a new functional activity also disrupt it`s thermodynamic stability. It then requires increased levels of chaperones to obtain it`s normal configuration than it usualy does.
HSP90 inhibitors are thus being investigated as potential cancer therapeutics.

Thank you, Darko. At least now, while my PC is chuddering away, I'll know more about what it's doing.
