E6, Human Papillomavirus type 16

25 μg

E6 (Early protein 6) is a viral protein produced in cells infected with the Human Papillomavirus. E6 forms a complex with the host cell ubiquitin ligase E6AP (E6-Associated-Protein) generating a ligase activity that polyubiquitinates tumor suppressors p53 and p73 and targets them to the 26S proteasome for degradation. As a result DNA damage and chromosomal instabilities increase, often leading to cell proliferation and cancer. The E6/E6AP complex also targets other substrates for ubiquitination, such as TERT, BAK1, FADD, and pro-CASP8—none of which appear to be substrates for E6AP in the absence of E6. This protein is untagged, and contains six cysteine-to-serine substitutions at positions 23, 58, 87, 104, 118, and 147 (HPV type 16 sequence numbering).
