USP9X deubiquitinates SMAD4. 13 / 13
1 | 12
reach
"For example USP9X may upregulate ID2 gene expression by deubiquitinating and stabilizing the transcription factor SMAD4 (Dupont et al., 2009)."
21925315
reach
"The deubiquitination of Smad4 by FAM is direct."
19135894
reach
"FAM and USP9X is required for TGFbeta induced migration of MDA-MB-231 breast cancer cells; mechanistically, FAM and USP9X inhibits the monoubiquitination of SMAD4, a modification that blocks the association of SMAD4 with phospho-SMAD2 [XREF_BIBR] (XREF_FIG)."
27844253
reach
"Subsequently it was shown that USP9X deubiquitylates SMAD4 that is monoubiquitylated at K519 (XREF_FIG)."
25007997
reach
"Usp9x promotes TGFbeta pathway signalling by deubiquitylating Smad4, allowing it to complex with phosphorylated receptor Smads and then shuttle into the nucleus to execute transcriptional responses to TGFbeta family ligands [XREF_BIBR]."
25672900
reach
"Taken together, these results demonstrate that USP9x selectively binds to SMAD4 in competition with TIF1gamma and deubiquitinates SMAD4, promoting nuclear SMAD4 retention, SMAD3 and SMAD4 complex formation and target gene expression."
28115363
reach
"USP9X (also known as FAM) deubiquitylates SMAD4 and thereby sustains TGF-beta signaling (Dupont etal."

"Multiple mono-ubiquitination of SMAD3 can be removed by USP15 and mono-ubiquitination of SMAD4 seems to be removed by FAM/USP9X."
25317929
reach
"This inhibitory event is readily reversed by FAM and USP9x, which deubiquitinates Smad4 and restores its responsiveness to TGF-beta [XREF_BIBR]."
20940046
reach
"USP9X reverses Smad4 ubiquitination to reactivate the pathway and reinstate TGFbeta signaling."
25606592
reach
"However, FAM/USP9x can reverse the ubiquitination of Smad4 and counteract the activity of TIF1γ in TGF-β/Smad signaling (30)."
31632911
reach
"Usp9x deubiquitylation of Smad4 is essential for signalling by members of the Tgf-beta family XREF_BIBR, XREF_BIBR."
23861879
reach
"In the cytoplasm, FAM and Usp9x deubiquitinates and recycles Smad4, re-empowering its competence to mediate TGFbeta signaling.We identified in Ecto a critical factor for Smad4 monoubiquitination at ly[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"
