"To investigate whether the α-synuclein protein stability is mediated by YOD1, Myc-YOD1 was transfected in a dose-dependent manner."

sparser
"In this study, we investigated the ubiquitination of Myc-YOD1 and Flag-USP21 using wild-type HA- Ub and various lysine mutant forms of it."

sparser
"To evaluate the effect of YOD1 on the stability of USP21, we transfected HEK293T, HeLa, and A549 cell lines with increasing doses of Myc-YOD1 and assessed the expression level of exogenous USP21."

sparser
"Additionally, we examined which lysine-linked polyubiquitin chain is associated with the proteasomal degradation of Myc-YOD1."

sparser
"Subsequently, we transfected increasing doses of Flag- USP21 into HEK293T, HeLa, and A549 cells to evaluate the stability change of Myc-YOD1."

sparser
"Surprisingly, each lysine mutant form of HA-Ub was capable of forming polyubiquitin chains on Myc-YOD1, and each type of lysine mutant form-linked polyubiquitin chain on Myc-YOD1 was related to proteasomal degradation (Fig.  xref C)."

sparser
"Interestingly, we found that the expression level of Myc-YOD1 remained unchanged in HEK293T cells exposed to Flag- USP21 (Fig.  xref C), and there was no significant difference in YOD1 stability observed in HeLa and A549 cells (Fig.  xref D)."

"For deubiquitination assay, Flag-α-synuclein, HA-ubiquitin-WT, its lysine mutants (HA-Ub + K6 , HA-Ub + K11 , HA-Ub + K27 , HA-Ub + K29 , HA-Ub + K33 , HA-Ub + K48 , and HA-Ub + K63 ), and Myc-YOD1 we[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

"We observed that the expression level of NEDD4 was significantly increased, and α-synuclein was decreased in a dose-dependent manner of Myc-YOD1 ( Fig. 4 A and B)."

sparser
"In the deubiquitination assay of Myc-YOD1, the formation of a polyubiquitin chain on Myc-YOD1 was reduced by Flag-USP21 compared to a catalytically inactive mutant of Flag-USP21 (C221S), indicating that USP21 functions as a DUB of YOD1 (Fig.  xref A)."

sparser
"Similarly, in the deubiquitination assay of Flag-USP21, the formation of a polyubiquitin chain on Flag-USP21 was reduced by Myc-YOD1 compared to a catalytically inactive mutant of Myc-YOD1 (C160S), indicating that YOD1 functions as a DUB of USP21 (Fig.  xref B)."
