It is vitally important, because misfolded proteins either do not work at all or do things that they shouldn't.
ECONOMIST: What video-game technology can do in the real world
Because the proteins surrounding elephant ova are similar to those from pigs, these antibodies attack the elephant ova, too.
It's a model that scientists have tried with spider silk before, but because the proteins in spider silk are so large, it takes some pretty wacky-sounding techniques to replicate them (like getting it from the milk of transgenic goats).
The powder that works in your washing machine at high temperature functions because it contains proteins extracted from microbes that grow in volcanic hot springs.
CNN: How the search for aliens can help sustain life on Earth
Because it's proteins that lead to reactions, technically a peanut has at least eight major food allergens, explaining why people with peanut allergies will have varying reactions, said the FDA's Luccioli.
Sutent made sense as a follow-up drug because it hit several defective proteins involved in cancer and, it was hoped, would get around the tumor cells' resistance.
This will be useful because the location and activity of receptor proteins on surface membranes can be a matter of life and death for a cell or a virus.
Officials packed long metal tubes -- called "carrier pigeons" -- with oxygen, vaccines and sustenance, liquid proteins and vitamins at first because the men were not ready for solid food.
Participants in immunotherapy studies have reported that they learned not to take their regulated allergen doses before exercising because it causes a faster absorption of proteins and can trigger a reaction, she said.
Because her lab's working with cells and proteins rather than mosquitoes and people, she can quickly and cheaply screen massive numbers of chemicals, even hundreds of thousands.
The decision to enter the DNA-decoding market came about because although PerkinElmer is big player in diagnostics and in the analysis of proteins, it had no real presence in DNA sequencing.
Diversa has attracted notice because of its unique method of producing human antibodies, which are disease-fighting proteins produced by the immune system.
The feeder cells cannot reproduce because they have been irradiated, but they provide the stem cells with the nutrients and proteins they need to divide and reproduce indefinitely.
FORBES: Aberrations Pose A Challenge for Reprogramming Stem Cells
Because Sangamo Chief Executive Edward Lanphier obtained exclusive licenses from the handful of academics working on zinc-finger proteins, Sangamo has a near lock on patents relating to zinc-finger proteins.
