Ubiquant
Ubiquant (九坤投资) is one of China's largest quantitative hedge funds, founded in Beijing in 2012 by two former Millennium quants, Wang Chen and Yao Qicong.
Ubiquilin
Ubiquilins are a family of conserved eukaryotic proteins that act as shuttle factors, delivering ubiquitin-tagged, misfolded proteins to the proteasome and autophagy systems; UBQLN2 mutations cause familial ALS with frontotemporal dementia.
Ubiquinol
Ubiquinol is the reduced, electron-rich form of coenzyme Q10 (CoQ10), a cofactor in every human cell that supports ATP production and acts as a lipid-soluble antioxidant.

Ubiquitin chain editing and remodeling
Ubiquitin chain editing and remodeling is the enzymatic trimming, proofreading, and restructuring of polyubiquitin chains by about 100 human deubiquitinating enzymes, which reshape rather than erase ubiquitin signals.
