ProteomicsSystematic Analysis of C-termini of Small Open Reading Frames Encoded Peptides in Human Cancer Cells
The C-terminal of proteins regulates their biological functions. Small open reading frame-encoded peptides (SEPs) are a novel class of gene expression products that participate in various biological activities. The C-termini of SEPs have also been found to affect their function, but the polymorphism...

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...

ProteomicsIdentification of novel smORFs acting in response to rehydration of Nostoc flagelliforme
Nostoc flagelliforme is able to recover biological activities within hours from months of anhydrobiosis state. In this work, we first constructed a smORF database, and analyzed the proteome of N. flagelliforme over rehydration.

ProteomicsIdentification of phosphorylated SEPs in Hep3B cells by LC/MS/MS
We identified phosphorylated SEPs in Hep3B cells. ACN precipitation, thermo precipitation and HCl precipitation were used to enrich SEPs. Three materials (nmTiO2, umTiO2, IMAC) were used to enrich phosphorylated peptides.

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...

ProteomicsDynamic expression of intra-and extracellular proteome and the influence of epiphytic bacteria for Nostoc flagelliforme in response to rehydration
In the present work, we analyzed the intra-and extracellular proteome of N. flagelliforme over a complete rehydration period both in sterilization and natural condition for the first time.

ProteomicsIdentification of small open reading frames-encoded peptides in Saccharomyces cerevisiae under different stress conditions
Here we used mass spectrometry-based proteomics technology to explore SEPs with potential cellular stress function in Saccharomyces cerevisiae. Microproteins with unique peptides were identified under six culture conditions: normal, oxidation, starvation, UV radiation, heat shock, and heat shock wit...

ProteomicsIdentification and analysis of small proteins and short open reading frame encoded peptides in Hep3B cell
The small proteins and short open reading frames encoded peptides (SEPs) are of fundamental importance because of their essential roles in biological processes. However, the annotation or identification of them is challenging, in part owing to the limitation of the traditional genome annotation pipe...

ProteomicsIdentification and analysis of short open reading frame encoded peptides in different brain regions of mice
Here we used mass spectrometry-based proteomics technology to explore SEPs with potential function in five brain regions of the mouse. SEPs with unique peptides were identified in hippocampus, frontal cortex, temporal cortex, occipital cortex and parietal cortex.
