They have determined that the virus takes the help of a protein present in our cells, an enzyme called USP46, which becomes essential for HPV-induced tumor formation and growth.
"It's an enzyme, and because it's an enzyme, it has a small pocket essential for its activity, and because drug companies are very good at producing small chemicals that will jam that pocket and make enzymes like USP46 inactive," said Dutta.
Curiously, HPV uses USP46 for an activity that is opposite to what the oncoprotein E6 was known to do.
Interestingly, the target genes of miR-3680-5p are USP2, USP6, USP46, and DLT, all of which are members of the UPS .
