Function
UCHL5_HUMAN Protease that specifically cleaves 'Lys-48'-linked polyubiquitin chains. Deubiquitinating enzyme associated with the 19S regulatory subunit of the 26S proteasome. Putative regulatory component of the INO80 complex; however is inactive in the INO80 complex and is activated by a transient interaction of the INO80 complex with the proteasome via ADRM1.[1] [2]

Publication Abstract from PubMed
Ubiquitin C-terminal hydrolases (UCHs) are one of five sub-families of de-ubiquitinating enzymes (DUBs) that hydrolyze the C-terminal peptide bond of ubiquitin. UCH37 (also called UCH-L5) is the only UCH family protease that interacts with the 19S proteasome regulatory complex and disassembles Lys48-linked poly-ubiquitin from the distal end of the chain. The structures of three UCHs, UCH-L1, UCH-L3, and YUH1, have been determined by X-ray crystallography. However, little is known about their physiological substrates. These enzymes do not hydrolyze large adducts of ubiquitin such as proteins. To identify and characterize the hydrolytic specificities of their substrates, the crystal structure of the UCH37 catalytic domain (UCH-domain) was determined and compared with that of the other UCHs. The overall folding patterns are similar in these UCHs. However, helix-3 is collapsed in UCH37 and the pattern of electrostatic potential on the surface of the putative substrate-binding site (P'-site) is different. Helix-3 comprises an edge of the P'-site. As a result, the P'-site is wider than that in other UCHs. These differences indicate that UCH37 can interact with larger adducts such as ubiquitin.
