摘要
Abstract Proteins need to acquire their native structure in order to become fully functional. In specific cases, active conformation is obtained spontaneously; nevertheless, many proteins need the assistance of chaperones and co-chaperones to be properly folded. These proteins help to maintain protein homeostasis under control conditions and under different stresses. HOP (HSP70-HSP90 Organizing Protein) is a highly conserved family of co-chaperones that assist HSP70 and HSP90 in the folding of specific proteins. In the last few years, exciting findings in mammals and yeast have revealed novel functions of HOP and re-defined the role of HOP in protein folding. In this article, we give an overview of the most important aspects of HOP regulation and function in other eukaryotes and analyze if these aspects are conserved in plants. In addition, we put special emphasis on the HOP clients described in plants and on the role of HOP in plant development and stress response.
