Researchers at the University of California San Francisco and Oxford Nanopore Technologies have demonstrated that a de novo designed protein can be installed inside an existing CsgG nanopore. This research-stage development shows that artificial proteins can be used to reshape the lumen of these biological channels.
Why it matters
The ability to precisely alter the architecture of a nanopore from within could enable more granular control over molecular transport and sensing. This collaboration explores how synthetic biology can expand the functionality of existing sequencing-grade pore variants.
The team grafted a de novo protein component onto a natural anchoring segment to secure it within the CsgG nanopore. This research demonstrates successful integration under extreme confinement, effectively modifying the internal dimensions of the pore lumen.
The players
University of California, San Francisco
A public research university recognized for its focus on health sciences, biotech innovation, and clinical research.
Oxford Nanopore Technologies
A biotechnology firm that develops and commercializes nanopore-based electronic systems for molecular analysis and sequencing.
The details
The researchers utilized a CsgG variant, a type of channel protein previously engineered for DNA sequencing, as a scaffold. By grafting a synthetic protein component onto a natural anchoring segment, the team forced the de novo protein into the interior of the existing pore. This study focuses on proving that such extreme confinement does not prevent the stable installation of artificial protein structures.

The Tech Race
This work advances the field of programmable biological sensors by extending the versatility of known nanopore scaffolds. It builds upon established CsgG sequencing technology by demonstrating that pore lumen architecture is no longer static.
This research is currently at the laboratory stage and does not yet affect commercial sequencing or clinical diagnostics. Users of nanopore technology should watch for subsequent studies on how this lumen modification alters the sensitivity and throughput of molecular detection.
The takeaway
The successful integration of de novo proteins into confined pores opens a new pathway for re-engineering the fundamental hardware of molecular sensors. Future progress will be measured by whether this modification can be scaled for consistent performance in commercial sequencing workflows.
