Finally out! Thrilled to share our collaboration with @kulathu.bsky.social, @orafurman.bsky.social, and N Davey. We screened auxiliary domains of USP family #deubiquitinases, revealing short linear motifs (SLiMs), contributing to specificity in complex assembly.

Systematic Discovery of Motif-based Interactions of the Auxiliary Domains of USP Family Deubiquitinases
The ubiquitin-specific proteases (USPs) family is the largest family of human deubiquitinating enzymes (DUBs). While most USPs are agnostic to polyubiquitin linkage-type, their substrate specificity i...

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).
