Allosteric proteins hydrophobic association

Identification of Hydrophobic Association with Rigor in Muscle and with the Tense, T-State, of Allosteric Proteins Exhibiting Positive Cooperativity... 

Ca2+ influx initiates protein and membrane associations by several different mechanisms. Allosteric regulation of the hydrophobicity of protein-binding surfaces frequently occurs. One of the best studied examples is the Ca2+-dependent binding of calmodulin to other proteins (Ch. 22). Annexins are a family of proteins that exhibit Ca2+-dependent associations with cell membranes through direct interaction with phospholipids, and conversely, interactions with phospholipids increase their affinities for Ca2+ [7].
