Evolution of growth factor signaling to the TSC complex to regulate mTORC1 Structural and evolutionary insights are discussed about how the primary brake on mTORC1 activity is lifted.

🧪 We have a new Review this week in Science Signaling by @bdmanning.bsky.social and colleagues on the structure and evolution of the TSC complex, which acts as a brake on #mTORC1.

Nice review on #TSC and #mTORC highlighting our cryoEM structure of TSC. Phosphorylation mechanisms that modulate TSC activity still remain unknown. TBC1D7 function largely a mystery, but important in brain development / megalencephaly.

Inspired predominantly by insightful cryo-EM structures from Yanhui Xu’s lab and @drellisdon.bsky.social on the TSC protein complex, which we have been focused on the regulation of upstream of mTORC1 for 23 years and counting. Enjoy!

Thrilled to share the structure of dimerised human PINK1 docked to an endogenous translocase array on the mitochondrial surface, composed of two TOM complexes, bridged by a VDAC2 dimer! Published today in Science www.science.org/doi/10.1126/...

It was perfectly clear last night until about 11pm which allowed me to finally have a good look at the Horsehead Nebula. Here is the result of 61 minutes of data (366 stacked images) from the Seestar S50. Slight enhancement in Lightroom.

The PDBs for our TSC structure are now available!

To put the size of TSC in perspective, here's a ribosome... this thing is enormous. 🤩

RCSB PDB - 9CE3: Structure of the TSC:WIPI3 lysosomal recruitment complex Structure of the TSC:WIPI3 lysosomal recruitment complex

The PDB files for the TSC:WIPI3 complex have been released today at the PDB. At 40nm across, it is well worth a look 😀🧪

I completely agree. I would only be guessing, but potentially a 12hr vs 24hr clock scheduling mistake?

Did someone mix up AM and PM over at the #NHMRC? I'm all for releasing grant outcomes as soon as possible, but 1:30 AM is a rather unconventional choice!
