"Using a functional genomic approach, we have identified ubiquitin-specific peptidase 4 (USP4) as a deubiquitinase for TAK1."
reach
"Although it has been reported that USP4 deubiquitinates TAK1 and negatively regulates TNF- and IL-1-induced activation of NF-kappaB, how TAK1 ubiquitination is regulated in adaptive immune cells such as T cells and whether such a regulation regulates T cell mediated immune response remain unknown."
reach
"In view of the data presented here and previous reports, we propose a working model (XREF_FIG), in which that TNFalpha rapidly induces Lys63 linked TAK1 polyubiquitnation and binding of USP4 to TAK1, Lys63 linked TAK1 would be rapidly deubiquitinated by USP4 to attenuate the magnitude of TNFalpha induced Lys63 linked TAK1 polyubiquitination and TAK1 mediated IKK and NF-kappaB activation."
