反射蛋白是最近发现的富含芳香族和含硫氨基酸的蛋白质家族，被某些头足类动物用于管理和操纵其环境中的入射光。这些蛋白质是纳米级光子结构的主要组成部分，其在静态和自适应着色中发挥作用，扩展视觉性能和种内通信。我们对重组表达的反射蛋白的研究揭示了意想不到的自组装和行为特性，我们证明了反射蛋白可以很容易地加工成薄膜，光子光栅结构和纤维。我们的研究结果代表了我们理解这个独特的反射蛋白家族的性质-功能关系的关键一步。
Reflectins, a recently identified protein family that is enriched in aromatic and sulphur-containing amino acids, are used by certain cephalopods to manage and manipulate incident light in their environment. These proteins are the predominant constituent of nanoscaled photonic structures that function in static and adaptive colouration, extending visual performance and intraspecies communication. Our investigation into recombinantly expressed reflectin has revealed unanticipated self-assembling and behavioural properties, and we demonstrate that reflectin can be easily processed into thin films, photonic grating structures and fibres. Our findings represent a key step in our understanding of the property-function relationships of this unique family of reflective proteins.
