Membrane lipid and protein adaptations in Antarctic fish
The success of Notothenioids to survive in the Antarctic involves, among other things, adaptive modifications of proteins and membrane lipids, because only the conservation of their biochemical characteristics and physiological state allows physiological processes to proceed at the low temperature o...

The success of Notothenioids to survive in the Antarctic involves, among other things, adaptive modifications of proteins and membrane lipids, because only the conservation of their biochemical characteristics and physiological state allows physiological processes to proceed at the low temperature of the Antarctic sea. Biological membranes are complex structures whose composition (mainly lipid and protein) and arrangement vary widely both between, and within, cells depending upon function (Gennis, 1989). The phospholipid bilayer holds multiple essential properties for cell membrane function since it: (i) acts as a physical barrier to solute diVusion; (ii) regulates the utilization of energy in transmembrane ion gradients; (iii) mediates the transmembrane movement of specific solutes; (iv) provides an organizing matrix for the assembly of multicomponent metabolic and signal transduction pathways; (v) supplies precursors for the generation of lipid-derived second messengers.
