I am a cell biologist who studies protein quality control and proteostasis in the secretory pathway with emphasis on GPI-anchored proteins, p24-family of proteins, calnexin, endoplasmic reticulum, Golgi, and lysosomes.

Exciting discovery by @iqbalhamzalab.bsky.social and colleagues! “These findings reveal intercellular heme sharing and identify HRG1 as a potential therapeutic target in hemoglobinopathies.”

Red blood cells don't always make their own heme - under stress, they scavange it from neighbors. Our new paper in @ScienceMagazine reveals a cell-nonautonomous heme acquisition pathway essential for erythroid hemoglobinization. #heme #erythropoiesis #anemia www.science.org/doi/10.1126/...

Ken Miller was my Cell Bio professor at Brown University. It’s my impression that his brilliant, thought-provoking, and often humor-infused presentations come straight from the heart. This is a “can’t miss” event TODAY at #cellbio2025 @ascbiology.bsky.social

Just one week away until #CellBio2025! Please plan to join us for a sUPeR speakER lineup at the #EndoplasmicReticulum Minisymposium! Dec 10 at 9 AM @ascbiology.bsky.social

Prasanna Satpute-Krishnan@pskcellbio.bsky.social · 9mo ago

Check out our @ascbiology.bsky.social #CellBio2025 Minisymposium on ER Homeostasis. With THIS speaker lineup, this event will be as dynamic, transformative and productive as the ER itself! So don’t 𝗦𝗧𝗥𝗘𝗦𝗦, 𝙩𝙧𝙖𝙣𝙨𝙡𝙤𝙘𝙖𝙩𝙚 yourselves over and join us to 𝗡𝗘𝗧𝗪𝗢𝗥𝗞 in world of the ER. (All PUNS intended.)

Thank you @jcellsci.bsky.social! It was so much fun chatting with Editor @seemagrewal.bsky.social about my journey, research, and advice for junior scientists. It’s great that it reads just like our conversation flowed. I sincerely hope it resonates with trainees out there! Read the interview 👇

tinyurl.com/mrce6bbb Fun to write this N&V together with Regina @hrshin.bsky.social, on the several cryoEM papers that build on her discovery of the fascinating LYCHOS protein and its role in cholesterol sensing and mTORC1 regulation!

Cholesterol finds its pocket in LYCHOS - Nature Structural & Molecular Biology

The lysosomal transmembrane protein LYCHOS enables activation of the master growth regulator mTORC1 kinase by cholesterol. Here we summarize recent structural findings that shed light on the LYCHOS ch...

This is a well written spotlight piece by Xin Xiang @xianglab.bsky.social highlighting a new discovery by Aquino et al in McNally lab. It describes a novel mechanism by which the kinesin-1-driven inward organelle packing pushes the spindle out towards the cortex. Interesting mechanism and biology!
