Structural host-virus interactome profiling of intact infected cells - Nature Communications Virus-host protein-protein interactions are fundamental to viral pathogenesis, yet few are structurally resolved. Here, the authors combine cross-linking mass spectrometry, bio-orthogonal labeling…

Excited to share: A Nature Communications study led by Fan Liu (Absea SAB Chair, FMP Berlin) introduces SHVIP—a method revealing 739 virus–host PPIs in intact HSV-1 infected cells.
It preserves membrane structure & uses AlphaFold to interpret complex networks.

Snapshot of in-cell protein contact sites reveals new host factors and hijacking of paraspeckles during influenza A virus infection Influenza A virus (IAV) hijacks host cellular machinery, but many virus-IAV interactions and contacting protein sites remain uncharacterised, particularly those dependent on intact cellular architectu...

Curious about other viruses? Then also check out how SHVIP is applied to Influenza A virus infection of human cells and how it led to the identification of novel host factors. Pre-print with @jankosinski.bsky.social lab: doi.org/10.1101/2025...

A big integrative effort! XL-MS: Lars Mühlberg, @juliaruta.bsky.social and @fan-liu.bsky.social. Infectious work: Iris Gruska, Barbara Vetter and Lüder Wiebusch. Modeling: @bioinfo.se

Why its relevant:
- It captures >700 PPIs and >6,000 cross-links
- It resolves compartment-specific interactions at the intact membrane system
- It integrates with AlphaFold to map domain-level PPIs, even in disordered regions
- It is validated by molecular virology + mutagenesis

SHVIP combines bio-orthogonal labeling during host shutoff and cross-linking mass-spec (XL-MS). XL-MS resolves proximity-based protein-protein interactions residue contact sites in situ and the bio-orthogonal labeling increases sensitivity of virus-specific interactome capture.

Building atomic models to cryo-EM maps of huge molecules is intimidating: crowded, uncertain copy numbers, variable resolution ...
Fan Liu and team incl us, show how cross-linking MS can be used to build novel models of unknown complexes, like a giant Melbourne virus
