Uch37 is one of the deubiquitinating enzymes of the human 26S proteasome, belongs to the Ub C-terminal hydrolases. Uch37 was found to bind both Adrm1 and S5a subunits of the 26S proteasome. Uch37 likely contributes to the Ub chain trimming activity of the 26S proteasome that shortens a polyUb chain from the distal end of the chain.
