AKT activates USP4. 3 / 3
| 3

reach
"Based on this study, it would be interesting to investigate whether USP4 function, which is also modulated by AKT as described above, is also affected in CYLD knockout mice XREF_BIBR."

reach
"According to a previous study by Iyengar [XREF_BIBR], Akt promotes USP4 to enter the cell membrane and cytoplasm to phosphorylate USP4 and regulate its subcellular localization, and Akt phosphorylation of USP4 occurs by combining with other de-ubiquitinating enzymes (DUBs) to de-ubiquitinate the TGF-beta receptor [XREF_BIBR]."

reach
"This study suggests that Akt activation in breast cancer cells induces USP4 to relocate and stabilize TbetaRI in the plasma membrane, and thereby enforces TGF-beta-induced pro tumorigenic responses."
