Human papillomavirus (HPV) is an infectious human virus of the skin. As most papillomaviruses do, HPV can cause papillomas, or skin lesions. low-risk HPV are much more common than high-risk HPV among humans and often do not cause any symptoms. In fact, only 18 types of HPV pose a cancer risk, mostly for anogenital cancers. Papillomaviruses are small, non-enveloped, icosahedral DNA viruses that have a diameter of 52–55 nm. The viral particles consist of a single double-stranded, circular DNA genome of about 8000 bp that contain approximately eight ORFs. The ORF can be divided into three functional parts: the early (E) region that encodes proteins (E1–E7) necessary for viral replication; the late (L) region that encodes the structural proteins (L1–L2) that are required for virion assembly; and a largely non-coding part that is referred to as the long control region (LCR), which contains cis elements that are necessary for the replication and transcription of viral DNA. The viral E proteins are transcribed from the early promoter (e.g. P97 in HPV 31) whereas the L proteins are transcribed principally from the late promoter (P742 in HPV 31).

  • HY-P72260
    Protein E6, HPV16 (His)

    E6; Protein E6

    		Virus E. coli
    HPV16 E6 is a viral phosphoprotein with oncogenic activity, belonging to the human papillomavirus early protein family. HPV16 E6 activates the cell cycle by releasing E2F through proteasome degradation of pRB. HPV16 E6 can cooperate with E6 to immortalize cells and neutralize the toxicity of E5, while activating the AP-1/NF-κB pathway and downregulating E-cadherin to enhance migration and invasion, making it a core target for cervical cancer. Protein E6, HPV16 (His) is a recombinant HPV E6 protein expressed from E. coli with an N-6*His tag.
  • HY-P72259
    Protein E7, HPV16 (His)

    E7; Protein E7

    		Virus E. coli
    HPV16 E7 is a viral phosphoprotein with oncogenic activity, belonging to the human papillomavirus early protein family. HPV16 E7 activates the cell cycle by releasing E2F through proteasome degradation of pRB. HPV16 E7 can cooperate with E6 to immortalize cells and neutralize the toxicity of E5, while activating the AP-1/NF-κB pathway and downregulating E-cadherin to enhance migration and invasion, making it a core target for cervical cancer. Protein E7, HPV (His) is a recombinant HPV E7 protein expressed from E. coli with an N-6*His tag.
  • HY-P700389
    Protein E7, HPV (N-His, C-His)

    Protein E7

    		Virus E. coli
    HPV protein E7 can induce dormant cells to enter the cell cycle and promote the efficient use of cellular DNA replication mechanisms for viral genome replication. Through translational and transactivation activities, E7 disrupts the RB1-E2F1 complex and activates E2F1-regulated S-phase genes. Protein E7, HPV (N-His, C-His) is the recombinant Virus-derived protein E7, HPV, expressed by E. coli , with N-6*His, C-6*His labeled tag.
