"Additionally USP21 may target not only ubiquitin conjugated substrates but also substrates conjugated to ubiquitin like proteins ISG15 and NEDD8 (Gong et al., 2000; Ye et al., 2011)."

reach
"Interestingly, we observed the opposite pattern with USP21, which rescued ubiquitin availability but was unable to rescue degradation of our panel of substrates."

"To further identify which Ub linkage type is targeted by USP25 in vivo, HEK-293T cells were transfected with HA-K48-Ub or HA-K63-Ub in lieu of HA-Ub."

reach
"Deletion of one or both UIM domains of USP25 does not alter C-terminal processing activity but strongly impairs K48 and K63 ubiquitin chain cleavage."
