五年前,我发表了《假设:钙调节蛋白包含EF-HANDS》。现在的同源物包括S-100、肠道钙结合蛋白、小白蛋白、肌球蛋白的调节和必要轻链、肌钙蛋白C,以及最重要的钙调蛋白。钙调节蛋白的定义是,它存在于细胞胞浆或面向胞浆的膜上,在胞浆条件下,它的钙亲和力pK,(Ca“)5到7。到目前为止,没有一种钙调节蛋白本身是酶。然而,通过它们的相互作用,它们赋予了广泛的细胞质酶和细胞过程钙调节。
Five years ago I published “Hypothesis: Calcium Modulated Proteins Contain EF-Hands.”’ The list of homologs now includes S-100, intestinal calcium-binding protein, parvalbumin, regulatory and essential light-chains of myosin, troponin C, and most important, calmodulin. A calcium-modulated protein is defined by its presence in the cell cytosol or on a membrane facing the cytosol and by its calcium affinity, pK, (Ca” ) 5 to 7 under cytosolic conditions. None of the calcium modulated proteins, characterized to date, are themselves enzymes. Yet by their interactions they confer calcium modulation on a wide variety of cytosolic enzymes and cell processes.
