"USP21 positively regulates and stabilizes GATA3, which can maintain FOXP3 expression."

"In a search for DUBs that contribute to GATA3 stabilization in FOXP3-expressing cells, both USP7 and USP21 were shown to upregulate GATA3-mediated activity using a reporter assay ."

"Interestingly, Foxp3 directly activates expression of USP21, and siRNA knockdown of USP21 downregulates both GATA3 and Foxp3 protein."

"Overexpression of USP21 can rescue GATA3 from its degradation so as to stabilize the expression of GATA3 [XREF_BIBR]; RT-PCR showed that the mRNA of USP21 is upregulated in the Treg cells of asthma patients."

"In summary, we have identified a USP21 mediated pathway that promotes GATA3 stabilization and expression at the post-translational level."
