    We hope this will be useful to the community. I plan to expand the document if needed as more questions and feedback come in. Let me know if there’s something you think should be included! 5/5

    For the computational proteomics folks, I’ve replicated what I had in a poster at ASMS in 2018. It includes the wrong turns we took in normalization and the diagnostics we used to assess different normalization methods 4/5

    For the computational biologists, we review the experimental design, the basics of how TMT works, how to interpret the normalized values, and how we’ve managed missing data. It also talks about the three replicate samples in the main data 3/5

    Even before the data were widely released we were getting questions from two groups of people. The first was computational biology analysts without much mass spec proteomics experience. The second was the proteomics community wanting details about the normalization. 2/5

    About a week and a half ago we published our paper and data for the quantitative proteomes of the Cancer Cell Line Encyclopedia. In response to questions we had about the data we’ve written a guide that’s up now on BioRxiv 1/5

    As my very first post on twitter, I am very excited to announce that our article "Identification of cancer driver genes based on nucleotide context" appeared in Nature Genetics today. Here is the link to our study:

    There’s engineered HEK293 lines that can be cultured in suspension!?! That’s amazing! ()

    This is the HMS write up of the incredible paper published this week from member Marian Kalocsay and Steven Marx at Columbia. Proximity labeling in a living heart!

    Phosphorylation is a post-translational modification with a vital role in cellular signaling. This study develops a workflow with FAIMS coupled to Orbitrap MS for a multiplexed analysis of tandem mass tag-labeled peptides

    There’s lots more in the paper, but we’re mostly excited to see how the community is able to use these data to advance our understanding of both cancer and basic cell biology. The data will be available with the paper, , and (13/13)

    Inspired by this we looked for consistent changes in other protein complexes associated with the sensitivity to different gene knockdowns and found such genes with associated complexes. These complexes hint at biochemical mechanisms underlying genetic sensitivity (12/13)

    Finding anything ribosome-associated with hypermutation was a surprise and the role of these complexes here is unknown. (11/13)

    In the CCLE, we found that expected complexes like mismatch repair were downregulated in MSI, but also several unexpected including two ribosome-associated complexes, SKI and RQC, that had no previous association with MSI. (10/13)

    We have a strong interest in protein complexes in the because of the project, which itself just announced an interaction map of the MSI cell line HCT116. So these efforts dovetailed nicely. (9/13)

    Turning to cancer, we were interested in how the proteome, might change under extremely high mutation burden. We ended up focusing on a particular form of cancer called microsatellite instability (MSI) and found surprising changes in several protein complexes. (8/13)

    This appears to be a broad correlated organization of the proteome that transcends tissue or pathway that’ve never seen before. This is because it doesn’t happen in RNA data. What organizes that? It looks like the mechanisms of transcription. (7/13)
