Ubiquitylome–proteome dataset of the red alga Gracilariopsis lemaneiformis

ABSTRACT: This integrated ubiquitylome–proteome dataset provides a comprehensive view of protein abundance and lysine ubiquitination dynamics in the commercially important red alga Gracilariopsis lemaneiformis under low-temperature stress. The ubiquitylome was profiled using anti-K-ε-GG antibody-based enrichment followed by high-resolution liquid chromatography–tandem mass spectrometry (LC-MS/MS), while the global proteome was quantified in parallel under the same experimental conditions. The dataset includes identification and quantification of thousands of proteins and ubiquitination sites, enabling systematic analysis of post-translational regulatory networks involved in cold stress response. This resource offers valuable insights into the molecular mechanisms of environmental adaptation in marine macroalgae and serves as a foundation for future functional studies on ubiquitin-mediated signaling in photosynthetic eukaryotes.

Rose petal whole protein and proteomics of phosphorylation and ubiquitination modification

Project description:The 4D label-free quantitative proteomics (4D-LFQ) was used for quantification of proteome changes. Enrichment of phosphorylated peptides using immobilized metal ion affinity chromatography (IMAC) and enrichment of ubiquitinated peptides using anti-diglycine remnant (anti-K-ε-GG) antibodywere performed in phosphoproteome and ubiquitylome, respectively. Phosphorylation and ubiquitination quantifications were normalized by protein quantifications to eliminate the interference caused by protein abundance differences.

Large-scale filter-aided sample preparation method for the analysis of the ubiquitinome

Project description:Protein ubiquitination regulates key cellular functions including protein homeostasis and signal transduction. The digestion of ubiquitinated proteins with trypsin yields a glycine-glycine remnant bound to the modified lysine residue (K-ε-GG) that can be recognized by specific antibodies for immunoaffinity purification (IAP) and subsequent identification of ubiquitination sites by mass spectrometry. Previous ubiquitinome studies based on this strategy have consistently digested milligram amounts of protein as starting material using in-solution digestion protocols prior to K-ε-GG enrichment. Filter-aided sample preparation (FASP) surpasses in-solution protein digestion in cleavage efficiency but its performance has thus far been shown for digestion of sample amounts on the order of micrograms. Because cleavage efficiency is pivotal in the generation of the K-ε-GG epitope recognized during IAP, here we developed a large-scale FASP method (LFASP) for digestion of milligram amounts of protein and evaluated its applicability to the study of the ubiquitinome. Our results demonstrate that LFASP-based tryptic digestion is efficient, robust, reproducible and applicable to the study of the ubiquitinome. We benchmark our results with state-of-the-art ubiquitinome studies and show an ~3-fold reduction in the proportion of miscleaved peptides with the method presented here. Beyond ubiquitinome analysis, LFASP overcomes the general limitation in sample capacity of standard FASP-based protocols and can therefore be used for a variety of applications that demand a large(r) amount of starting material.

Quantitative Proteomic Atlas Uncovering the widespread Ubiquitylation regulation in the Embryo of Germinating Rice Seed

Project description:Using high affinity K-Ɛ-GG antibody integrating highly sensitive MS, we investigated the quantitative atlas of ubiquitylome as well as the proteome in the embryos of germinated rice seed. A total of 7507 proteins were identified, and 5018 were precisely quantified, the mass errors and peptides length distribution showed the high mass accuracy, andthe PCA result displayed the well repeatability (Figure S3, Table S2). Of these quantified proteins, 764(65.3%) were found in the ubiquitylome, this high overlapping ascribed to the high resolution of MS.

Proteomes and Ubiquitylomes Analysis Reveals the Involvement of Ubiquitination in Protein Degradation

Project description:Petal senescence is a complex programmed process. It has been previously demonstrated that treatment with ethylene, a plant hormone involved in senescence, can extensively alter transcriptome and proteome profiles in plants. However, little is known regarding the impact of ethylene on post-translational modification (PTM) or the association between PTM and the proteome. Protein degradation is one of the hallmarks of senescence, and ubiquitination, a major PTM in eukaryotes, plays important roles in protein degradation. In this study, we first obtained reference petunia transcriptome data via RNA sequencing. Next, we quantitatively investigated the petunia proteome, ubiquitylome, and the association between them in petunia corollas following ethylene treatment. In total, 51,799 unigenes, 3,606 proteins, and 2,270 ubiquitination sites were quantified 16 hours after ethylene treatment. Treatment with ethylene resulted in 14,448 down-regulated and 6,303 up-regulated unigenes (absolute log2-fold change >1 and FDR<0.001), 284 down-regulated and 233 up-regulated proteins, and 320 up-regulated and 127 down-regulated ubiquitination sites using a 1.5-fold threshold (P<0.05), indicating that global ubiquitination levels increase during ethylene-mediated corolla senescence in petunia. Several putative ubiquitin ligases were up-regulated at the protein and transcription levels. Our results showed that the global proteome and ubiquitylome were negatively correlated and that ubiquitination could be involved in the degradation of proteins during ethylene-mediated corolla senescence in petunias. Ethylene regulates hormone signaling transduction pathways at both the protein and ubiquitination levels in petunia corollas. In addition, our results revealed that ethylene increases the ubiquitination levels of proteins involved in ER-associated degradation (ERAD).

Proteomic analysis of protein ubiquitination events in human primary and metastatic colon adenocarcinoma tissues

Project description:Protein ubiquitination is essential for multiple physiological processes through regulating the stability or function of target proteins and has been found to play critical roles in human cancers. However, the protein ubiquitination profile of human metastatic colon adenocarcinoma tissue has not been elucidated yet. In this study, a proprietary ubiquitin branch (K-ε-GG) antibody-based label-free quantitative proteomics and bioinformatics were performed to identify the global protein ubiquitination profile between human primary (Colon) and metastatic colon adenocarcinoma (Meta) tissues.

Ubiquitination modification omics

Project description:Protein ubiquitination plays a vital role in the stress response of diverse filamentous fungi. However, few reports are available on fungal insect pathogens including Metarhizium. Here, we report a comparative ubiquitylome analysis of M. robertsii exposed to heat stress. The growth of M. robertsii was suppressed and protein ubiquitination levels were markedly promoted during heat stress. Compared to the control treatment, there were 4,674 sites with differential ubiquitination, of which 3,419 lysine ubiquitination sites across 1,344 proteins were significantly up-regulated, and 1,255 sites on 750 proteins were down-regulated under heat stress. Further analysis showed that these proteins with up-regulated modified sites were preferentially enriched in the phenylalanine, tyrosine, and tryptophan biosynthesis, pantothenate and CoA biosynthesis, and O-glycan biosynthesis pathways. Proteins with down-regulated modified sites were significantly enriched in different pathways including alanine, aspartate, and glutamate metabolism, pyruvate metabolism, and fatty acid biosynthesis. In particular, a key protein (phosphoenolpyruvate carboxykinase, MrPCK1, a central enzyme in gluconeogenesis and pyruvate metabolism) with five ubiquitination sites was identified, and functional analysis further revealed its regulatory role in heat stress tolerance of M. robertsii. Taken together, our findings suggest that M. robertsii may respond to heat stress not only through the canonical pathway of the proteasome but also by modulating specific metabolic pathways, including pyruvate metabolism (notably via MrPCK1) and potentially fatty acid biosynthesis. The results provide insights into the molecular mechanisms by which ubiquitination regulates the heat stress response in M. robertsii and contribute to our understanding of thermotolerance in filamentous fungi.
