Human papillomavirus type 18
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Transcriptional transactivator. Binds double-stranded DNA (By similarity). Has transforming activity. Inactivates, with E6-AP ubiquitin-protein ligase, the human p53/TP53 tumor suppressor protein by targeting it to degradation. Binds and targets human MUPP1/MPDZ protein to degradation. Those two functions presumably contribute to transforming activity. Interaction with human FBLN1 protein also seems to be linked to cell transformation.By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
