Monoclonal antibodies against pseudaminic acid (Pse) – present in bacterial LPS, capsular polysaccharides, and glycoproteins – have been developed that enable Pse glycoproteome profiling and show therapeutic potential #glycotime

Really happy to see this work out!

Super fun project with a great team. For me the highlight was that we finally were able to show the O-linked glycosylation systems of H. pylori/C. jejuni are general glycosylation systems which target non-flagellin proteins (suggest >10 years ago by click chem).

Phosphoproteomics of aged insulin-resistant bone identifies P70S6K phosphorylation of AFF4 as a gene-specific transcriptional regulator - Nature Communications Insulin signaling plays a crucial role in coordinating skeletal development with whole‑body energy metabolism. Here, the authors use phosphoproteomics to show insulin-signaling rewiring in aged, insul...

Our #phosphoproteomics analysis of insulin signaling in bone uncovered a new mechanism of transcriptional activation via S6K phosphorylation of AFF4. It appears to play a role in regulating the expression of genes in ageing and insulin resistance. www.nature.com/articles/s41...

🚨 Our new paper is out today in Nature Chemical Biology:
“Pan-specific antibodies to uncover bacterial pseudaminylation”
doi.org/10.1038/s415...

This is the product of a collaboration between many teams, led by @nickescott.bsky.social, @payneresearch.bsky.social and myself.

Quantitative interactome mapping of skeletal muscle insulin resistance Protein-protein interactions (PPIs) are dynamic and critical to adaptive homeostasis. While there have been massive efforts to catalogue proteome-wide PPIs, global quantification of changes remains a ...

Protein:protein interactions are incredibly dynamic so how do we quantify and discover changes in native tissues? Our new study uses qXL-MS and PCP-MS to study dynamic remodeling of interactions following skeletal muscle insulin resistance. #MyoBlue #Proteomics www.biorxiv.org/content/10.6...

Super thrilled to have this one accepted at AnalChem last week. Nice way to see out the end of the year. 🎉 #lipidomics #TeamMassSpec

Welcome to the club, what instrument are you generating the data on (QE?) can provide guidance, drop me an email.... Looking at the raw data, upping your AGC and using stepped nce is going to be your friend here

Conventional proteomics searches struggle with many modifications and fully open searches may be difficult to interpret. We introduce a "detailed" mass offset search in #MSFragger boosting interpretability and localization especially in complex cases (e.g. FPOP data): www.biorxiv.org/content/10.1...

The late-stage steps of Burkholderia cenocepacia protein O-linked glycan biosynthesis are conditionally essential Periplasmic O-linked protein glycosylation is a highly conserved process observed across the Burkholderia genus. Within Burkholderia, protein glycosylation requires the five-gene cluster known as the ...

Really nice to see this work finally out in print. This has been a long term project (> 3 years) in the lab to understand why we couldn't make a few mutants in the burkholderia o-linked glycan biosynthesis pathway. Special shout out to Leila who drove most of this work! www.jbc.org/article/S002...

📣 Calling all students! 📣

Did you know that ANZSMS have travel support for attending ANZSMS conferences and international mass spectrometry conferences? 😮

The deadline for students attending the 30th ANZSMS at AUS-oMicS this year is coming up next week, 18th March! 🚨

Congratulations!! Very well deserved!

Regardless of current events, highlighting trainees as they continue to excel is a joy.

We just added @emmajays.bsky.social's recent J_@asms.org publication about chemical deamidation from common proteomics buffer to our website, too.

Congrats Emmajay! #TeamMassSpec

Really cool stuff, this looks super specific to cys. Looking at the ms2 data do labelled peptides show any unique diagnostic ions?

Ha! Not my only bright jersey on this trip

For those interested in the distance cycled, not bad considering there was two days of travel in there

I rarely post personal things on here but it's my birthday and as it's the big 4-0 I've spent the week cycling in south east Asia which has been awesome.. 100% recommend cycling around Siem Reap in Cambodia

⏰ Time’s ticking! Only 2 weeks left to submit your oral presentation abstract for #AUSoMicS 2025!

Salmonella multimutants enable efficient identification of SPI-2 effector protein function in gut inflammation and systemic colonization Salmonella enterica spp. rely on translocation of effector proteins through the SPI-2 encoded type III secretion system (T3SS) to achieve pathogenesis. More than 30 effectors contribute to manipulatio...

Excited to share this story describing new tools for studying Salmonella virulence. We engineered six multimutant strains to be deficient for different sets of SPI-2 T3SS effectors. We think there's lots of potential for new discoveries using these strains www.biorxiv.org/content/10.1...
