ProteomicsMapping subcellular localizations of unannotated microproteins with MicroID
Proteogenomic and ribosome profiling identification of translated small open reading frames have revealed thousands of microproteins, or polypeptides of less than 100 amino acids, that were previously invisible to geneticists. However, the vast majority of microproteins remain uncharacterized in mol...

ProteomicsIdentification of microproteins in Hep3B cells at different cell cycle stages
Microproteins are generated from small open reading frames (sORFs) and turn out to play various vital biological functions. As an essential biological event of eukaryotic cells, the cell cycle is involved in cell replication and division. For such a highly regulated event, microproteins associated w...

ProteomicsMapping microproteins and ncRNA-encoded polypeptides in different mouse tissues
Small open reading frame encoded peptides (SEPs), also called microproteins, play a vital role in biological processes. Plenty of their open reading frames are located on the non-coding RNA (ncRNA) range. Recent research has demonstrated that ncRNA-encoded polypeptides have essential functions and e...

ProteomicsCovalent Organic Framework with Acid Precipitation Enhances Microprotein Enrichment and Discovery of Ferroptosis-Associated Microproteins
Microproteins, defined as polypeptides fewer than 100 amino acids, are encoded by small open reading frames (sORFs) and exhibit unique structural and functional characteristics. Despite their short length and recent discoveries, microproteins have already been found to play critical roles in diverse...

ProteomicsMiPRISMA: Interactome profiling of small peptides and young microproteins translated from human short open reading frames Part4
All species continuously evolve small open reading frames (sORFs) that can be templated for protein synthesis and may provide raw material for evolutionary adaptation. We analyzed the evolutionary origins of 7,264 recently cataloged human sORFs and found that most were evolutionary young and emerged...

TranscriptomicsCharacterization of miP1a/b (microProteins) overexpression plants, including a constans mutant (co-SAIL)
MicroProteins are short, single domain proteins that act by sequestering larger, multidomain proteins into non-functional complexes. MicroProteins have been identified in plants and animals, where they are mostly involved in the regulation of developmental processes. Here we show that two Arabidopsi...

ProteomicsComparative proteomic profiling of unannotated microproteins and alternative proteins in human cell lines
Ribosome profiling and mass spectrometry have revealed thousands of small and alternative open reading frames (sm/alt-ORFs) that are translated into polypeptides variously termed microproteins and alt-proteins in mammalian cells. Some micro-/alt-proteins exhibit stress-, cell type- and/or tissue-spe...

ProteomicsProteogenomic Profiling Reveals Functional Microproteins in T Cells
Noncanonical micropeptides, i.e., polypeptides mostly under 10 kDa, are encoded by genomic sequences that have been previously annotated as noncoding but now known as small open reading frames (sORFs). The recent identification of microproteins encoded by sORFs has provided evidence that many sORFs ...
