reach
"ATXN3L deubiquitinates KLF5."

reach
"We then sought to determine whether ATXN3L directly decreases the KLF5 ubiquitination."

reach
"The ATXN3L protein interacted with the KLF5 protein and decreased the KLF5 polyubiquitination."

"Ataxin-3 like (ATXN3L), a member of the Josephin family of deubiquitinating enzymes, promotes breast cancer proliferation by deubiquitinating Kruppel-like factor 5 (KLF5).

The Kr眉ppel-like factor 5 (KLF5) has been suggested to promote breast cell proliferation, survival and tumorigenesis."

reach
"GST-ATXN3L, but not GST-ATXN3L (M4), dramatically decreased the KLF5 protein polyubiquitination."

reach
"Whether the deubiquitination of KLF5 protein by ATXN3L is regulated is unknown at present."

reach
"Although ATXN3L decreases the KLF5 protein ubiquitination, ATXN3L may have other substrate proteins."

reach
"As shown in Figure XREF_FIG, ATXN3L silencing increased the endogenous KLF5 protein ubiquitination."
