Latest Patents

One of Ai Kaiho's latest patents is a method for determining ubiquitin chain length. This invention addresses the challenges in documenting ubiquitin chain lengths, which have been overlooked for decades. The method, named 'ubiquitin protection from trypsinization' (Ub-ProT), allows for the determination of the actual length of substrate-attached polyubiquitin chains from biological samples. The findings indicate that the mean length of these chains falls within the dimer to decamer range. Additionally, quantitative proteomics revealed that the mean lengths of five major types of ubiquitin chains can be categorized into two groups. Notably, proteasome inhibition did not affect the mean length of substrate-attached polyubiquitin chains, suggesting a robust regulatory system within cells.
