生物分子,例如,一种酶,往往与它的许多同源底物、靶或伙伴有差异地相互作用。这种性质被称为相对特异性,并已被提出来调节重要的生理功能,即使它还没有在大多数复杂的生化系统中明确检查。本文综述了近年来在蛋白质折叠、信号转导、RNA结合、翻译和转录等方面的大规模研究。这些结果和其他支持的相对特异性在不同的生物过程中的普遍作用。越来越清楚的是,相对特异性从根本上有助于生物系统的多样性和复杂性,这对疾病过程也有重要影响。
A biological molecule, e.g., an enzyme, tends to interact with its many cognate substrates, targets, or partners differentially. Such a property is termed relative specificity and has been proposed to regulate important physiological functions, even though it has not been examined explicitly in most complex biochemical systems. This essay reviews several recent large-scale studies that investigate protein folding, signal transduction, RNA binding, translation and transcription in the context of relative specificity. These results and others support a pervasive role of relative specificity in diverse biological processes. It is becoming clear that relative specificity contributes fundamentally to the diversity and complexity of biological systems, which has significant implications in disease processes as well.
