dMAD7 is a promising tool for targeted gene regulation in the methylotrophic yeast Komagataella phaffii.

The methylotrophic yeast Komagataella phaffii is a popular host system for the pharmaceutical and biotechnological production of recombinant proteins. CRISPR-Cas9 and its derivative CRISPR interference (CRISPRi) offer a promising avenue to further enhance and exploit the full capabilities of this host. MAD7 and its catalytically inactive variant "dead" MAD7 (dMAD7) represent an interesting alternative to established CRISPR-Cas9 systems and are free to use for industrial and academic research.

Computational Prediction of Disordered Protein Motifs Using SLiMSuite.

Short linear motifs (SLiMs) are important mediators of interactions between intrinsically disordered regions of proteins and their interaction partners. Here, we detail instructions for the computational prediction of SLiMs in disordered protein regions, using the main tools of the SLiMSuite package: (1) SLiMProb identifies and calculates enrichment of predefined motifs in a set of proteins; (2) SLiMFinder predicts SLiMs de novo in a set of proteins, accounting for evolutionary relationships; (3) QSLiMFinder increases SLiMFinder sensitivity by focusing SLiM prediction on a specific query protein/region; (4) CompariMotif compares predicted SLiMs to known SLiMs or other SLiM predictions to identify common patterns. For each tool, command-line and online server examples are provided.
