  • 功能：
    Multifunctional protein that acts as a viral transcriptional activator. Promotes read-through of an RNA hairpin in the NP open reading frame to enhance viral transcription. Mechanistically, nonphosphorylated VP30 hexamers form a ternary complex with the viral leader RNA. Clamps the RNA template and the complex VP35-polymerase L together, thereby increasing the polymerase affinity for the RNA template to increase transcription initiation despite the presence of RNA secondary structures. Assists also stop-start transcription at gene junctions to promote transcription of downstream genes. Interaction with NP plays a critical role in transcription initiation by recognizing the RNA stem loop. Interaction with host RBBP6 interferes with NP-VP30 interaction and inhibits viral RNA synthesis. Also acts as a suppressor of RNA silencing by interacting with host DICER1 and TARBP2/TRBP.

    1. Functional analyses of the eVP30-nucleoprotein interface identify residues that are critical for viral RNA synthesis. Altogether, these results support a model where the eVP30-nucleoprotein interaction plays a critical role in transcription initiation and provides a novel target for the development of antiviral therapy. PMID: 28593988
    2. Comparison of the percentage of disorder (PID) in nucleocapsid proteins VP30 and NP reveals high correlation between nucleocapsid PIDs and the case-fatality rates of Ebola virus . PMID: 26086270
    3. mutations of Thr(143) and Thr(146) of VP30 significantly inhibited EBOV transcription and strongly induced VP30 phosphorylation in the N-terminal Ser residues 29-46, suggesting a novel mechanism of regulation of VP30 phosphorylation. PMID: 24936058
    4. Study shows for the first time the direct interaction of EBOV VP30 with RNA and the importance of the N-terminal region for binding RNA. PMID: 17567691
    5. VP30 is involved in reinitiation of gene transcription and that this activity is affected by mutations at the phosphorylation sites. PMID: 18829754
