TransitID is out today in Cell! This is a proximity labeling method for unbiased discovery of endogenous proteins that traffick from a defined “source” location to a defined “destination” location. TransitID uses sequential labeling by TurboID in the source, followed by a chase period (minutes to hours) and then 1-minute APEX tagging in the destination compartment. Proteins tagged by both enzymes are enriched with streptavidin and anti-fluorescein antibody, and identified by mass spec.

We explore 4 intracellular and intercellular applications of TransitID:
- discovery of locally translated mitochondrial proteins (translated at OMM, then imported into mito matrix)
- mapping proteins whose cytoplasm-to-nucleus shuttling is dampened by stress
- discovery of proteins that transit between nucleolus & stress granules during stress & stress recovery
- analysis of proteins that traffic intercellularly bw tumor cells & macrophages

I am so excited, next week I will be defending my PhD dissertation!

I am happy to share the zoom link for the public seminar to anyone who would like to join on Tuesday Aug 23 at noon!

@LindnerLab does kidsbop cover jazz? I thought they only did the hits, like Call Me Maybe

@KevinHartPhD hehe different kind of bop Kev, more kylie minogue than kinetoplastids

After extensive annotation and analysis our main analysis of TrypTag, the subcellular localisation of every trypanosome parasite protein, is up on biorXiv. https://t.co/FTrogkQGZM

[Kelly Rios @KellyTRios]

This is particularly important for those of us who want to study transmissible gametocytes, and other means to enrich for sexual blood stage populations should be considered.

[Kelly Rios @KellyTRios]

My first first-author research article from my PhD with @LindnerLab is now online! 🥳

Us rodent malaria researchers routinely use sulfadiazine to select for sexual blood stage parasites in the host, but we asked if this drug exposure affects transmission.

[Kelly Rios @KellyTRios]

Turns out, sulfa exposure in the rodent host or the mosquito vector limits mosquito stage development in vivo!

And the effects of sulfadiazine exposure are reversible, as washing out the drug allows for fertilization and ookinete development in vitro.
