ATXN3 deubiquitinates KLF4. 8 / 9

reach
"For example, studies have shown that ATXN3 can promote breast cancer metastasis by deubiquitinating KLF4."

reach
"ATXN3, a deubiquitinating cysteine enzyme, deubiquitinates KLF4 in breast cancer [208]."

reach
"29 Moreover, recent reports have found that ATXN3 promotes breast cancer metastasis by deubiquitinating KLF4."

reach
"Additionally, ATXN3 was highly expressed in breast cancer and it promotes tumor tissue metastasis by deubiquitinating and stabilizing KLF4 [46]."

reach
"However, the mechansims of ATXN3 up-regulation in breast cancer, how KLF4 promotes breast cancer, and whether aberrant deubiquitination of KLF4 by ataxin-3 is involved in the pathophysiology of MJD, remain to be explored.Another example of ataxin-3's capacity to regulate gene expression via its DUB function is evident in its interaction with histone deacetylase 3 (HDAC3)."

reach
"Our data show that ATXN3 interacts with KLF4 to antagonize KLF4 ubiquitination."

reach
"We also elucidated that ATXN3 promotes breast cancer metastasis by deubiquitinating and stabilizing KLF4, revealing the role of the KLF4 deubiquitinating process in breast cancer metastasis and sugges[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

"Furthermore, in breast cancer, ATXN3 promotes metastasis by deubiquitinating KLF4, a transcription factor frequently overexpressed in various human cancers and closely associated with tumorigenesis and tumor progression (16)."
