After a long journey and much hard work from many talented scientists, our paper is finally out. Take a look if you are interested in proteases and host microbe interactions in the gut. www.cell.com/cell-host-mi...
A Bacteroides fragilis protease activates host PAR2 to induce intestinal pain and inflammation
Lakemeyer and colleagues analyze the secretome of gut bacteria to identify factors that target host PAR2. They find that the Bacteroides fragilis protease Bfp1 cleaves and activates PAR2, disrupting i...

Engineered bispecific Notch agonists โ€œpullโ€ on and mechanically activate Notch receptors in the presence of desired biomarkers

Engineering synthetic agonists for targeted activation of Notch signaling - Nature Chemical Biology
The development of soluble Notch agonists is a challenge because of the mechanical forces needed to activate Notch receptors. Here, bispecific Notch agonist proteins were designed that โ€˜pullโ€™ on and activate Notch receptors in the presence of desired biomarkers.

Wowโ€”thank you so much Evelina! We have long been inspired by your work! Please let us know what you see (and let us know if we can help!). ๐Ÿ˜Ž

Many thanks, Gal!!! Weโ€™re excited to see the paper live online! =)

Thanks Brian! it was a a fun project led by two super talented students. Glad you like the movies! ๐Ÿ˜Ž

3๏ธโƒฃ Future synthetic biology utilities:

Right now, we are fusing these proteins to #synbio effectors and adaptors to:
โ€ข control RNA fate,
โ€ข boost CRISPR/dCas9 RNA scaffolds,
โ€ข reduce off-target labeling
enabling next-gen RNAโ€“protein circuits for synthetic regulation and control.

2๏ธโƒฃ Advantages in Imaging & Controlling Single mRNAs:

โ€ข Single-mRNA sensitivity using 1ร—mNeonGreen fusions in live #imaging

โ€ข Track the localization & translation #mRNAs encoding cytoplasmic, nuclear, mitochondrial & secreted proteins

โ€ข Direct #mRNA localization by fusing dMCP to targeting signals
September 22, 2025 at 6:27 PM
1๏ธโƒฃ Mechanism & protein engineering:

Through circular permutation + degron masking, we designd dMCP & dPCP to be rapidly degraded unless bound to their cognate #RNA hairpins (MS2 & PP7). Hairpin binding switches them from unstable to bright, RNA-bound reporters via a #degron masking mechanism.

๐Ÿš€ Our new paper is out @natmethods.nature.com!

Kuffer & Marzilli engineered conditionally stable MS2 & PP7 coat proteins (dMCP & dPCP) that degrade unless bound to RNA, enabling ultraโ€“low-background, single-mRNA imaging in live cells.
