CYLD inhibits CYLD. 8 / 9

reach
"Additionally, phosphorylation of CYLD was found to downregulate CYLD activity : transient phosphorylation by IKK in a serine cluster just upstream of the TRAF2 binding site, attenuates DUB function XREF_BIBR."

reach
"The CYLD staining and protein expression were lower in the OX-LDL+ Sal A group than OX-LDL group after culturing for 48 hours (P < 0.01, Figures XREF_FIG - XREF_FIG and XREF_FIG), revealing that OX-LDL increases CYLD level and Sal A antagonizes OX-LDL by downregulating CYLD."

reach
"Together, these observations demonstrate that IKKepsilon mediated phosphorylation of CYLD at Ser418 inhibits CYLD deubiquitinase activity."

reach
"Phosphorylation of CYLD at Ser418 decreases CYLD activity."

reach
"However, constitutive phosphorylation of CYLD by IKK inactivates CYLD in HTLV-1-induced leukemia to promote heightened NF-kappaB activation."

reach
"These results demonstrate that phosphorylation of CYLD at Ser418 suppresses CYLD activity, resulting in increased NF-kappaB transcriptional activation."

reach
"As IKK mediated phosphorylation of CYLD has been reported to negatively regulate CYLD enzymatic activity [XREF_BIBR], we further explored whether IKK is also involved in regulating the degradation of CYLD by SCF beta-TRCP."

reach
"Interestingly, recent findings also suggest that OTULIN deficiency results in spontaneous inhibitory phosphorylation of CYLD, thereby limiting CYLD activity, which can be rescued by LUBAC inhibition [XREF_BIBR]."
