Proteins at membrane surfaces-a review of approaches

Mol Biosyst. 2007 Oct;3(10):705-13. doi: 10.1039/b708581h. Epub 2007 Aug 21.


Membrane proteins are critical for normal cellular differentiation and function, and alterations in these proteins often leads to cell dysfunction and disease. Membrane proteomics aims to identify the membrane protein constituents, their posttranslational modifications, protein-protein interactions, and dynamics. Efforts to identify membrane proteins and elucidate their dynamics have been plagued by the challenges presented by studying water insoluble proteins that are distributed among a range of membranes in a cell and often occur at a relatively low abundance. This brief review presents a summary of the literature related to membrane proteomics with an emphasis on efforts to develop effective protocols for the enrichment of membrane proteins, particularly those located in the plasma membrane.
