Rpn10 is a ubiquitin receptor of the 26S proteasome, and plays an important role in poly-ubiquitinated proteins recognition in the ubiquitin-proteasome protein degradation pathway. It is located in the 19S regulatory particle and interacts with several subunits of both lid and base complexes. Bioinformatics analysis of yeast Rpn10 suggests that it contains a von Willebrand (VWA domain) and a C-terminal tail containing a Ub-interacting motif. Studies of Saccharomyces cerevisiae Rpn10 suggested that its VWA domain might participate in interactions with subunit from both lid and base subcomplexes of the 19S regulatory particle. Herein, we report the chemical shift assignments of (1)H, (13)C and (15)N atoms of the VWA domain of S. cerevisiae Rpn10, which provide the basis for further structural and functional studies of Rpn10 by solution NMR technique.
Rpn10是26S蛋白酶体的泛素受体,在泛素-蛋白酶体蛋白降解途径中对多泛素化蛋白的识别起重要作用。它位于19S调节颗粒中,并与盖子和底座复合物的几个亚基相互作用。对酵母Rpn10的生物信息学分析表明,它包含一个血管性血友病因子(VWA结构域)和一个含有泛素相互作用基序的C末端尾巴。对酿酒酵母Rpn10的研究表明,其VWA结构域可能参与与19S调节颗粒的盖子和底座亚复合物亚基的相互作用。在此,我们报告了酿酒酵母Rpn10的VWA结构域的(1)H、(13)C和(15)N原子的化学位移归属,这为通过溶液核磁共振技术对Rpn10进行进一步的结构和功能研究提供了基础。
