Technologies for plasma membrane proteomics

Technologies for plasma membrane proteomics.

Cell-cell and intracellular signaling are critical mechanisms by which an organism can respond quickly and appropriately to internal or environmental stimuli. Transmission of the stimulus to effector proteins must be coordinated, rapid and transient such that the response is not exaggerated and the overall balance of the cell or tissue is retained. Proteomics technology has traditionally been a...

An effective plasma membrane proteomics approach for small tissue samples

Advancing the quest for new drug targets demands the development of innovative plasma membrane proteome research strategies applicable to small, functionally defined tissue samples. Biotinylation of acute tissue slices and streptavidin pull-down followed by shotgun proteomics allowed the selective extraction and identification of >1,600 proteins of which >60% are associated with the plasma memb...

Plant plasma membrane proteomics for improving cold tolerance

Plants are always exposed to various stresses. We have focused on freezing stress, which causes serious problems for agricultural management. When plants suffer freeze-induced damage, the plasma membrane is thought to be the primary site of injury because of its central role in regulation of various cellular processes. Cold tolerant species, however, adapt to such freezing conditions by modifyi...

Application of Proteomics Technologies in the Drug Development Process

Mass spectrometry technologies for proteomics.

In the late 1980s, the advent of soft ionization techniques capable of generating stable gas phase ions from thermally unstable biomolecules, namely matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization (ESI), laid the way for the development of a set of powerful alternatives to the traditional Edman chemistry for the structural characterization of peptides and protein...
