ProteomicsPooled overexpression screening identifies PIPPI as a novel microprotein involved in the ER stress response
Microproteins encoded by short open reading frames (sORFs) of less than 100 codons have been predicted to constitute a substantial fraction of the eukaryotic proteome. However, relevance and roles of the majority of microproteins remain undefined because only a small fraction of these intriguing cel...

OtherhnRNPA is a novel regulator of a mitochondrial microprotein expression
Mitochondrial-derived peptides (MDPs) are microproteins that are encoded by short open reading frames within the mitochondrial genome. Several MDPs have been identified in recent years; however, the transcriptional and translational regulation of MDPs remain poorly understood. Here we discovered an ...

ProteomicsA Novel Mitochondrial Microprotein Reprograms Cellular Bioenergetics and Protects Against Hepatic Steatosis
Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a major global health challenge with limited therapeutic options. To identify new regulators of lipid metabolism, we developed a novel proteomic strategy combining organelle enrichment with a custom sORF database to explore ...
