This graph basically shows that the MSCA are, as of now, useless unless the EU governance does something about it 🧪

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

Schematic showing the function of Sgt1 in yeast.

Our latest work is now out in @cp-molcell.bsky.social !
We have looked at Sgt1, an essential Hsp90 co-chaperone in yeast. We determined its interaction with Hs90 and showed that it stabilises the chaperone-client complex and prevents its dissociation by Aha1.

The essential co-chaperone Sgt1 regulates client dwell time in the Hsp90 chaperone cycle Engler et al. define the Sgt1-specific domain as essential for the Sgt1 chaperone function in yeast. Through structural and biochemical analyses, they uncover unique interactions of Sgt1 with Hsp90 and client proteins that enhance client maturation efficiency. Sgt1 stabilizes Hsp90-client complexes by preventing their dissociation mediated by the co-chaperone Aha1.

Triple Labeling Resolves a GPCR Intermediate State by Using Three-Color Single Molecule FRET The correlation of individual conformational changes in dynamic protein complexes remains challenging as most structural methods rely on averaged information over a large number of molecules. Single molecule FRET is a powerful tool for monitoring such conformational changes. When performed using three distinct probes, it enables the correlation of domain movements by providing up to three simultaneous distance measurements with high temporal resolution. Nevertheless, a major challenge lies in the site-specific attachment of three probes to unique positions within the target protein. Here, we propose an orthogonal triple-labeling strategy that is not compromised by native, reactive amino acid functionalities. It combines genetic code expansion and bioorthogonal labeling of two different noncanonical amino acids with an enzymatic self-labeling SNAP tag. We demonstrate its application by establishment of a 3-color sensor on the human metabotropic glutamate receptor 2, a dimeric, multidomain G protein-coupled neuroreceptor, and describe a previously unknown conformational intermediate state using 3-color single molecule FRET.

Our new study is out !
We introduce a triple labeling strategy (2 non canonical Amino Acids + 2 click chemistries and 1 SNAP-tag) to triple label a G-protein coupled receptor.
