NFRKB activates UCHL5. 8 / 8
| 8

reach
"While the DEUBAD domain of RPN13 activates UCH-L5 by increasing its affinity for substrates, in INO80G it does the opposite and dramatically decreases the affinity for substrates."

reach
"To determine whether NFRKB also modulates Uch37 activity, we affinity purified from insect cells recombinant Uch37 in complexes with NFRKB, various NFRKB derivatives, or hRpn13 (XREF_SUPPLEMENTARY) and assayed Uch37 for its ability to react with ubiquitin vinylsulfone (UbVS)."

reach
"Why does NFRKB DEU fail to activate Uch37?"

reach
"Our observations are consistent with the findings that RPN13 competes with NFRKB 1-101 for binding to UCH37 and that NFRKB residues 1-101 activate UCH37 but that the longer full-length and 1-465 constructs inhibit UCH37, as do the 39-156 and 1-117 constructs used in this study."

reach
"Enzyme kinetics analysis confirmed that INO80G short activates UCH-L5 on Ub-AMC (XREF_FIG B)."

reach
"INO80G short, containing only the helices alpha2-alpha4 of the DEUBAD domain, can activate UCH-L5, demonstrating that the core DEUBAD fold is already sufficient to bind and provide modest activation."

reach
"Our data show how UCH-L5 activity can be modulated by DEUBAD domains present in RPN13 and INO80G through remarkably large conformational changes."

reach
"Intriguingly, an artificial shorter version of INO80G was found to activate UCH-L5 invitro."
