In this paper we summarize the various factors that must be considered in establishing the operational specificity of the binding of a protein regulator of gene expression to a DNA target site. We consider informational (combinatorial) aspects of binding-site specification, actual recognition mechanisms, and the thermodynamics of target-site selection against a background of competing pseudospecific and non-(sequence)-specific DNA binding sites. The results provide insight into the design, specification, and possibly the evolution of regulatory proteins and their chromosomal binding targets, as well as into practical aspects of the design of regulatory-protein isolation schemes and physicochemical regulatory considerations in vivo.
在本文中,我们总结了在确定基因表达的蛋白质调节因子与DNA靶位点结合的操作特异性时必须考虑的各种因素。我们考虑了结合位点特异性的信息(组合)方面、实际识别机制,以及在竞争性假特异性和非(序列)特异性DNA结合位点背景下靶位点选择的热力学。这些结果为调节蛋白及其染色体结合靶标的设计、特异性以及可能的进化提供了见解,同时也为调节蛋白分离方案的设计以及体内物理化学调节考虑的实际方面提供了见解。
