USP28 deubiquitinates KDM1A. 5 / 6
1 | 5

reach
"USP28 functions as a bona fide deubiquitinating enzyme for LSD1, as it interacts with and stabilizes LSD1 through the process of deubiquitination."

reach
"The results above suggest that USP28 may stimulate EMT via its deubiquitination of LSD1 and Snail and then suppress EMT-related molecules.In addition to the molecules involved in EMT, other molecules, such as Lin28A, which is a crucial regulator of invasiveness, can also accelerate metastasis [84]."

reach
"Therefore, USP28 can maintain Notch signaling, through which cell differentiation is inhibited.Moreover, LSD1, which can be deubiquitinated by USP28, has the capacity to regulate pluripotency markers such as octamer-binding transcription factor 4 (Oct4) and SRY-related HMG box-containing 2 (SOX2) and the differentiation gene p21 [9, 83, 91]."

reach
"We found that WT-USP28, but not CI-USP28, specifically removed LSD1 ubiquitination (XREF_FIG), indicating that USP28 directly deubiquitinated LSD1."

reach
"USP7 and USP28 inhibited LSD1 ubiquitination and stabilized LSD1 protein level [XREF_BIBR, XREF_BIBR]."
