The organisation of the cell membrane: do proteins rule lipids?

The organisation of the cell membrane: do proteins rule lipids? Curr Opin Chem Biol. 2014 May 8;20C:54-59 Authors: Rossy J, Ma Y, Gaus K Abstract Cell membranes are a complex adaptive system: they are constantly re-organised in response to extra- and intracellular inputs and their local and global structure ultimately determines how, where and when these inputs are processed. This requires a tight coupling of signalling and membranes in localised and specialised compartments. While lipids are essential components of cell membranes, they mostly lack a direct link to the input signals. Here we review how proteins can deform locally membranes, modify and reorganise lipids to form membrane domains and regulate properties like membrane charges and diffusion. From this point-of-view, it appears that proteins play a central role in regulating membrane organisation. PMID: 24815858 [PubMed - as supplied by publisher]
