Happy to share our newest preprint on Parkin missense variants in work led by Erna Sol & @vvouts.bsky.social in @rhp-lab.bsky.social Using a multiplexed assay we determined the effects of 9,212 out of 9,300 single amino acid substitutions and nonsense Parkin variants. 1/n doi.org/10.64898/202...

We map the effects of >99% Parkin (PRKN) missense variants on mitophagy. The landscape separates benign & pathogenic variants, reveals misfolded variants induce mitophagy and flags hypomorphic alleles for rescue. Collab w. @lindorfflarsen.bsky.social. Work led by Erna Sol & @vvouts.bsky.social.

Now on bioRxiv: genome‑wide CRISPR KO reveals BAG6 (chaperone) and RNF126 (E3) as core PQC for non‑native missense proteins. VAMP seq. shows >1000 Parkin variants are BAG6 targets, including known pathogenic variants. Work led by Line Pedersen. Collab with @lindorfflarsen.bsky.social

Second preprint of the year in which @sarahgersing.bsky.social from @rhp-lab.bsky.social mapped the effects of >7500 variants in glucokinase (GCK) on the interaction with the glucokinase regulatory protein so that we now have a 3D GCK scan (abundance, interaction, activity) doi.org/10.64898/202...
Figure 2 from the paper with: (A) Heatmap showing the interaction score of each possible amino acid substitution along the GCK sequence. (B) Interaction score distributions of missense, synonymous and nonsense variants.  (C) The median interaction score of each GCK residue mapped onto the structure of the GCK–GKRP complex.

New preprint! Led by @sarahgersing.bsky.social we map how 7,500+ variants in glucokinase (GCK) affect binding to GKRP and disentangle this from stability. We now have activity, abundance, and interaction scores for 7,128 GCK variants - a resource for understanding phenotypes and glucose homeostasis.

The proteasome-substrate-shuttle protein UBQLN2 contains—like other quality control system proteins—a long region devoid of lysine (a lysine desert) Martin Grønbæk-Thygesen (from @rhp-lab.bsky.social) et al show that introducing K here causes ubiquitylation and degradation doi.org/10.1101/2025...
Fig. 1 – UBQLN2 is a conserved lysine-depleted protein. (A) Sequence comparison of
UBQLN2 orthologs in the indicated species. Intrinsically disordered regions in human
UBQLN2 based on MobiDB are shown as a blue bar. The domain organization based on the
SMART database is marked. Lysine residues are marked as black squares. (B) ESM-2
predictions of all possible single amino acid substitutions of human UBQLN2 presented as a
heat map. The wild-type residues are marked in blue. ESM-2 scores close to zero (light
yellow colors) indicate that the amino acid substitution is compatible with the ESM-2
language model, whereas negative scores (dark orange colors) indicate that the variant is
incompatible with the ESM-2 model. The domain organization (based on SMART) is aligned
above the map. Note that substitutions to lysine or cysteine in general appear detrimental, in
particular downstream of the UBL domain. (C) The AlphaFold2 predicted structured of
human UBQLN2 (AF-Q9UHD9-F1) (left panel). The UBL domain is colored blue, and the
UBA domain is colored orange and the STI1 regions green. Zoom in on the UBL domain
(right panel) with the lysine residues highlighted as stick representations and colored based
on the relative accessible surface area (rASA, dark red exposed; grey, buried).

Martin Grønbæk-Thygesen in @rhp-lab.bsky.social measured abundance and toxicity (both independently of function) of missense variants in aspartoacylase, and found that a subset of the low-abundance variants were toxic, induced a stress response which correlated with toxicity doi.org/10.1038/s414...

Both translational and fundamental curiosity-driven research are needed to fuel the incredible progress we're seeing in genomic medicine; an important message in this article and and some lovely quotes from @sarahlwynn.bsky.social www.ft.com/content/25dd...

Curiosity underlies a breakthrough in rare disease

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.

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. Link to paper: www.cell.com/structure/fu...
cell.com
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.
