USP13 deubiquitinates PTEN. 18 / 19

reach
"In contrast, USP13 directly binds and deubiquitylates PTEN to suppress tumorigenesis and glycolysis in PTEN-positive breast cancer cells (35)."

reach
"Deubiquitylation and stabilization of PTEN by USP13."

reach
"In addition to its oncogenic roles, USP13 exerts a tumor-suppressive role by deubiquitinating PTEN in different types of cancers."

reach
"Wild-type USP13 purified from either bacteria or 293T cells, but not its catalytically inactive mutant C345A, decreased PTEN poly-ubiquitination by 64-70% in vitro (XREF_FIG)."

reach
"On the other hand, ectopic expression of wild-type USP13, but not the C345A mutant which is still capable of interacting with PTEN (XREF_FIG), reduced the poly-ubiquitination of PTEN by 65% (XREF_FIG), suggesting that the enzymatic activity of USP13 is indispensable for USP13 dependent deubiquitination of PTEN."

reach
"For example, USP13 prevents tumor cell growth by deubiquitinating PTEN in breast cancer, OSCC and bladder cancer."

reach
"Therefore, USP13 can directly deubiquitinate PTEN."

reach
"PTEN is deubiquitinated by USP13 in bladder cancer, and its stabilized expression suppresses tumor progression (127)."

reach
"PTEN is ubiquitinated by WWP2 and NEDD4 [ 49 , 50 ] and is deubiquitinated by USP13 and OTUD3 [ 19 , 20 ]."

reach
"Deubiquitination of PTEN by USP13, a deubiquitinating enzyme, stabilized PTEN, and thereby inhibited breast cancer tumorigenesis [5]."

reach
"USP13, another PTEN deubiquitinase, different with USP7-mediated deubiquitination of PTEN monoubiquitination, it reverses PTEN polyubiquitination, thus promoting the PTEN stabilization and tumor suppr[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"In these tumors, USP13 interacts with and deubiquitinates the tumor suppressor PTEN protein, thereby stabilizing and increasing the expression of PTEN [16–18]."

reach
"Ubiquitin-specific peptidase 13 (USP13) can deubiquitinate the PTEN protein and stabilize it."

reach
"Our findings revealed that USP13 alleviates MASH by directly binding to and deubiquitinating PTEN."

reach
"The decreased expression of USP13 promoted PTEN ubiquitylation, leading to PTEN degradation, thereby contributing to fibroblast activation and pathogenesis of IPF [101]."

reach
"Deubiquitination and stabilization of PTEN by USP13."

reach
"USP13 deubiquitinates and stabilizes PTEN."

reach
"However, Zhang et al. revealed that USP13 can deubiquitinate and stabilize the PTEN protein, thus inhibiting the Akt pathway and suppressing breast cancer progression [18]."
