靶點詳情

功能：

Plays a role in the initiation of viral DNA replication. A dimer of E2 interacts with a dimer of E1 in order to improve specificity of E1 DNA binding activity. Once the complex recognizes and binds DNA at specific sites, the E2 dimer is removed from DNA. E2 also regulates viral transcription through binding to the E2RE response element (5'-ACCNNNNNNGGT-3') present in multiple copies in the regulatory regions of the viral genome. Activates or represses transcription depending on E2RE's position with regards to proximal promoter elements including the TATA-box. Repression occurs by sterically hindering the assembly of the transcription initiation complex.
基因功能參考文獻：
1. Anti-E2, -L1, and -p16(INK4A) antibodies in sera were determined by western blot. Among 116 samples, 69 (60%) were HPV DNA-positive. Percentages seropositive for anti-E2, -L1, and -p16(INK4A) antibodies were 39.6, 22.4, and 23.3%, respectively. PMID: 29744680
2. The papillomavirus E8;E2 protein shares the hinge domain with E2 and acts as a repressor of viral replication. A large fraction of HPV31 E8;E2 is phosphorylated at S78 in the hinge region, and this is important for E8;E2's repression activity. Surprisingly, phosphorylation at S78 in E8;E2 has no impact on viral replication in tissue culture but rather seems to modulate the expression of a small number of cellular genes. PMID: 29167339
3. The papillomavirus E2 protein has splicing-related activities. (Review) PMID: 27867028
4. HPV E2 protein targets Rad50-interacting protein 1 (Rint1) to facilitate virus genome replication. PMID: 28031358

19. Consistent with prior reports, TopBP1 co-localized in discrete nuclear foci and was in complex with papillomavirus E2 protein. PMID: 25666521
