靶點詳情

功能：

Contributes to multiple aspects of the viral life cycle including viral genome amplification, suppression of suprabasal cell differentiation and egress of newly formed virions. Induces host cell cycle arrest at the G2 phase by associating with and preventing the nuclear entry of host CDK1/cyclin B1 complexes. Inhibits cellular DNA replication by preventing loading of host replication licensing proteins MCM2 and MCM7 onto chromatin. Within the cytoplasm, associates with host kinase SRPK1, a splicing factor regulator, and inhibits its activity. Therefore, E4 favors expression of late viral transcripts by inhibiting SRPK1-mediated phosphorylation of host serine-arginine (SR) proteins that have critical roles in mRNA metabolism. Late in the infectious cycle, E4 also acts to diminish the integrity of the keratinocyte by disrupting the keratin cytoskeleton and inducing apoptosis through alteration of mitochondrial function to facilitate egress of the newly formed virions.

3. 20 cervical cyology samples with HPV16 were tested by RT-PCR for HPV16 E4 mRNA, found in sqaumous intraepithelial lesion and squamous carcinoma, but not in samples negative for intrepithelial lesion. E4 expression assay may be useful in cancer diagnosis. PMID: 22299437
4. The data suggest a model in which the expression of 16E5 from the major E1--E4-E5 mRNA promotes T57 phosphorylation of E1--E4 by ERK and keratin binding. PMID: 19211765
