London, Apr 22: While proteins are known to be at the centre of every life process, and carry out all sorts of work by going to the cell, what guides these basic molecules towards their target cells in the brain has been unknown, until now.
Don Arnold- a molecular and computational biologist at USC College-and colleagues have now solved the mystery for key proteins in the brain.
"There''s no little man sitting there, putting the protein in the right place. Proteins have to have in them encoded information that tells them where to go in the cell," Nature quoted Arnold as saying.
