E6 inhibits CYLD. 6 / 6
| 6

reach
"The E6 oncoprotein is also able to promote the uniquitination and proteasomal degradation of the negative NFκB regulator cytlindromatosis (CYLD) lysine 63 deubiquitinase, in hypoxic conditions, common[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"It is also plausible that post-translational hydroxylation may take place on a protein involved in formation of a protein complex that includes E6 and CYLD, whereby hydroxylation impairs complex formation and, by extension, the ability of E6 to target CYLD for ubiquitination."

reach
"In cancer cell lines, infected with high-risk human papillomavirus (HPV) serotypes, HPV-encoded E6 protein ubiquitinates and degrades CYLD leading to prolonged NF-κB activation [ 28 ]."

reach
"Importantly, degradation of CYLD by E6 was prevented by treatment of cells with the proteasome inhibitor, MG132 (XREF_FIG)."

reach
"As HPV16 E6 inactivates CYLD XREF_BIBR and because defective CYLD causes enhanced nuclear import of BCL-3, we reasoned that HPV16 E6 may induce KIAA1199 expression through BCL-3 in transformed keratinocytes."

reach
"In preclinical models, under hypoxic conditions, the HPV encoded E6 protein promotes inactivation and degradation of the CYLD tumor suppressor, resulting in prolonged activation of NF-kappaB pathway [XREF_BIBR]."
