A Humanized Yeast Model for Studying TRAPP Complex Mutations; Proof-of-Concept Using Variants from an Individual with a TRAPPC1-Associated Neurodevelopmental Syndrome

Author(s): Zykaj E; Abboud C; Asadi P; Warsame S; Almousa H; Milev MP; Greco BM; López-Sánchez M; Bratkovic D; Kachroo AH; Pérez-Jurado LA; Sacher M;

Variants in membrane trafficking proteins are known to cause rare disorders with severe symptoms. The highly conserved transport protein particle (TRAPP) complexes are key membrane trafficking regulators that are also involved in autophagy. Pathogenic genetic variants in specific TRAPP subunits a ...

Genome sequencing of 15 acid-tolerant yeasts

Author(s): Bagley JA; Pyne ME; Exley K; Kevvai K; Wang Q; Whiteway M; Martin VJJ;

We report draft genome sequences for 15 non-conventional Saccharomycotina yeast strains obtained from public culture repositories. Included in our collection are eight strains of Pichia with broad tolerance to dicarboxylic acids. The genome sequences of these strains will enable comparative genomics of acid-tolerant phenotypes and strain engineering of no ...

Species-specific protein-protein interactions govern the humanization of the 20S proteasome in yeast

Author(s): Sultana S; Abdullah M; Li J; Hochstrasser M; Kachroo AH;

Yeast and humans share thousands of genes despite a billion years of evolutionary divergence. While many human genes can functionally replace their yeast counterparts, nearly half of the tested shared genes cannot. For example, most yeast proteasome subunits are "humanizable", except subunits comprising the ß-ring core, including ß2c (HsPSMB7, a constitut ...

Rapid, scalable, combinatorial genome engineering by marker-less enrichment and recombination of genetically engineered loci in yeast

Author(s): Abdullah M; Greco BM; Laurent JM; Garge RK; Boutz DR; Vandeloo M; Marcotte EM; Kachroo AH;

A major challenge to rationally building multi-gene processes in yeast arises due to the combinatorics of combining all of the individual edits into the same strain. Here, we present a precise and multi-site genome editing approach that combines all edits without selection markers using CRISPR-Ca ...

Pathway elucidation and microbial synthesis of proaporphine and bis-benzylisoquinoline alkaloids from sacred lotus (Nelumbo nucifera)

Author(s): Pyne ME; Gold ND; Martin VJJ;

Sacred lotus (Nelumbo nucifera) has been utilized as a food, medicine, and spiritual symbol for nearly 3000 years. The medicinal properties of lotus are largely attributed to its unique profile of benzylisoquinoline alkaloids (BIAs), which includes potential anti-cancer, anti-malarial and anti-arrhythmic compounds. BIA biosynthesis in sacred lotus differs ...

The MyLo CRISPR-Cas9 Toolkit: A Markerless Yeast Localization and Overexpression CRISPR-Cas9 Toolkit

Author(s): Bean BDM; Whiteway M; Martin VJJ;

The genetic tractability of the yeast Saccharomyces cerevisiae has made it a key model organism for basic research and a target for metabolic engineering. To streamline the introduction of tagged genes and compartmental markers with powerful CRISPR-Cas9-based genome editing tools we constructed a Markerless Yeast Localization and Overexpression (MyLO) CRI ...

Humanized yeast to model human biology, disease and evolution

Author(s): Kachroo AH; Vandeloo M; Greco BM; Abdullah M;

For decades, budding yeast, a single-cellular eukaryote, has provided remarkable insights into human biology. Yeast and humans share several thousand genes despite morphological and cellular differences and over a billion years of separate evolution. These genes encode critical cellular processes, the failure of which in humans results in disease. Althoug ...

Discovery of new vascular disrupting agents based on evolutionarily conserved drug action, pesticide resistance mutations, and humanized yeast

Author(s): Garge RK; Cha HJ; Lee C; Gollihar JD; Kachroo AH; Wallingford JB; Marcotte EM;

Thiabendazole (TBZ) is an FDA-approved benzimidazole widely used for its antifungal and antihelminthic properties. We showed previously that TBZ is also a potent vascular disrupting agent and inhibits angiogenesis at the tissue level by dissociating vascular endothelial cells in newly formed blood vessels. Here, we uncover TBZ's molecular target and m ...
