MetabolomicsQuantitative trait loci analysis identifies a prominent gene involved in the production of fatty-acid-derived flavor volatiles in tomato
To gain insight into the genetic regulation of lipid metabolism in tomato, we conducted metabolic trait loci (mQTL) analysis following the lipidomic profiling of fruit pericarp and leaf tissue of the Solanum pennellii introgression lines. To enhance mapping resolution for selected fruit-specific mQT...

TranscriptomicsValidation of the C. elegans model using juglone as a positive control for oxidative stress
To confirm the suitability of C. elegans as a model organism, preliminary gene expression experiments were performed using juglone (5-hydroxy-1,4-naphthoquinone; 97% pure; Sigma-Aldrich, St-Louis, MO), an ROS-generator, as a positive control of oxidative stress (d'Arcy Doherty et al. 1987; Leiers et...

ProteomicsDistinct mechanistic, conformational and substrate selectivity profiles emerging in the evolution of high catalytic activity enzymes via parallel trajectories
Recent laboratory evolution studies have demonstrated that parallel evolutionary trajectories can lead to genetically distinct enzymes with high activity towards a non-preferred substrate. However, it is unknown whether such genetically distinct enzymes have convergent conformational dynamics and me...

ProteomicsHydrogen-deuterium exchange mass spectrometry of wt Mtr4 with various RNA substrates
Mtr4 is a eukaryotic RNA helicase required for RNA decay by the nuclear exosome. Previous studies have shown how RNA enroute to the exosome threads through the highly conserved helicase core of Mtr4. Mtr4 also contains an arch domain, although details of potential interactions between the arch and R...

ProteomicsHistone variant H2A.Z enhances histone and nucleosome dynamics
Interchanging canonical histone H2A with variant H2A.Z in chromatin complexes is vital for the proper regulation of transcription, DNA damage repair, and centromere maintenance. However, the physical mechanisms underlying functional differences between H2A and H2A.Z complexes are unclear. Human H2A ...

ProteomicsMORC2 phosphorylation fine tunes its DNA compaction activity
Variants in the poorly characterized oncoprotein, MORC2, a chromatin remodeling ATPase, lead to defects in epigenetic regulation and DNA damage response. MORC2 variants are associated with multiple cancers and neurological disorders. The C-terminal domain (CTD) of MORC2is often phosphorylated in DNA...

ProteomicsHDX-MS of the TRAMP Complex with tRNA
TRAMP is a eukaryotic protein complex with RNA helicase and polyadenylase activity that marks and delivers a variety of RNA substrates to the nuclear exosome for degradation. Prior work has characterized binding of Trf4 and Air2 to the helicase core of Mtr4 and the regulation of both enzymatic activ...
