With the @lindorfflarsen.bsky.social group we present our map of degrons in all human transcription factors, incl. examples of constitutive degrons in exposed regions & buried degrons that are exposed upon mutation. In addition, we show that most TADs overlap with degrons. Work led by Fia Larsen.
Comprehensive degron mapping in human transcription factors
Gene expression is regulated by the targeted degradation of transcription factors through the ubiquitin-proteasome system. Transcription factors destined for degradation are recognized by E3 ubiquitin...

In our newest preprint we map degrons for >5,000 cytosolic proteins and we develop a degron predictor that can predict novel degron formation, a potential mechanism of pathogenicity. Many thanks to @rhp-lab.bsky.social, @lindorfflarsen.bsky.social and @dougfowler.bsky.social for their supervision.
A complete map of human cytosolic degrons and their relevance for disease
Degrons are short protein segments that target proteins for degradation via the ubiquitin-proteasome system and thus ensure timely removal of signaling proteins and clearance of misfolded proteins fro...

In collaboration with the @lindorfflarsen.bsky.social group we release our map of degrons in >5,000 human cytosolic proteins with >99% coverage. A machine learning model trained on the data identifies missense variants forming degrons in exposed & disordered regions. Work led by @vvouts.bsky.social.

Do you think that cooperativity requires more than one binding site or subunit? Or just want to read about an interesting enzyme for which both gain- and loss-of-function variants can cause metabolic disease?

In our new paper we characterize the effects of indel variants on protein folding and stability using a new yeast-based protein folding sensor. The work was led by Sven Larsen-Ledet and supported by the @novo-nordisk.bsky.social.

Systematic characterization of indel variants using a yeast-based protein folding sensor
Larsen-Ledet et al. developed a yeast-based protein folding sensor to determine the effects of indel variants in DHFR. Using a saturated indel library, it was found that most indels are not tolerated. Several are temperature sensitive and folding is rescued by methotrexate. Rosetta and AlphaFold2 predictions correlate with the observed effects.
