Protein E6 is one of three cancer proteins encoded by human papillomavirus (HPV). The binding of Protein E6 to ubiquitin protein ligase can inhibit the expression of p53. Protein E6 suppresses the immune response through the JAK-STAT signaling pathway. Protein E6 can promote cell proliferation and inhibit cell apoptosis. Protein E6, HPV16 (His) is the recombinant Virus-derived protein E6, HPV16, expressed by E. coli , with N-6*His labeled tag.

Virus

Protein E6 is an oncoprotein that plays a major role in the induction and maintenance of cell transformation by stimulating many host cell key regulatory proteins. Protein E6 binds to host ubiquitin protein ligase UBE3A/E6-AP to degrade and inactivate tumor suppressors TP53 and TP73 by targeting the 26S proteasome. In turn, DNA damage and chromosomal instability increase, leading to cell proliferation and cancer development. Protein E6 forms complexes that degrade E6/E6AP, including BAK1, Fas associated death domain protein (FADD), and procaspase 8 to inhibit apoptosis. Protein E6 also suppresses the immune response by interacting with host IRF3 and TYK2. These interactions block IRF3 transcriptional activity and inhibit interferon-α-mediated Tyk2-mediated JAK-STAT activation, thereby inhibiting the interferon signaling pathway. Protein E6 activates telomerase in early human keratinocytes and breast epithelial cells. The interaction between Protein E6 and hDLG or other proteins containing the PDZ domain may be a potential mechanism for the development of HPV-associated cancers [1] [2] [3] [4] [5] .
