Exploratorymetabolic regulationAspscr1/TUGcell culture systems and mouse tissuesproposed
Investigation of how the TUG C-terminal cleavage product enters the nucleus and interacts with transcriptional regulators. The study examined binding interactions between the TUG cleavage product and peroxisome proliferator-activated receptor (PPAR)γ and its coactivator PGC-1α. Researchers used biochemical approaches to demonstrate direct protein-protein interactions and functional consequences for gene transcription, particularly genes involved in lipid oxidation and thermogenesis.
PRIMARY OUTCOME
protein-protein interactions and transcriptional activity
EXPECTED OUTCOMES
Direct binding between TUG fragments and PPARγ/PGC-1α, enhanced transcriptional activity
SUCCESS CRITERIA
Demonstrated protein interactions and increased transcription of target genes
PROTOCOL
Nuclear fractionation, co-immunoprecipitation, transcriptional reporter assays, chromatin immunoprecipitation
