This is the result of a fantastic collaboration with @drellisdon.bsky.social at @monashuniversity.bsky.social, including first authors @luptoncj.bsky.social and @charlesbj.bsky.social, and co-lead Yong-Gang (Tyler) Chang. Special mention to Jade Dong and Terrance Lam from my team.

The latest research from our team is out in Cell @cp-cell.bsky.social! We used #cryo-EM, #imaging, #BRET, and #biosensors targeted to the lysosome to understand how the KICSTOR-GATOR1 complex turns off #mTORC1 in response to low levels of amino acids.

Structure of the lysosomal KICSTOR-GATOR1-SAMTOR nutrient-sensing supercomplex This study reveals how KICSTOR and GATOR1 assemble into a crescent-shaped lysosomal complex that regulates mTORC1 during amino acid starvation and how SAMTOR binds KICSTOR in an S-adenosylmethionine-incompatible conformation to couple methionine sensing to mTORC1 regulation.

Hox-C12 coordinates β2-adrenoceptor coupling to a cAMP/calcium feedforward loop to drive invasion in triple-negative breast cancer A GPCR and a moonlighting transcription factor together drive metastasis in breast cancer.

New work in #ScienceSignaling may answer why some patients with triple-negative breast cancer who receive beta-blockers have a lower risk of metastasis and identifies a factor that holds promise as a prognostic and therapeutic target. https://scim.ag/45XmD0b

Our latest paper from @monashuniversity.bsky.social Monash Institute of Pharmaceutical Sciences led by #PhD student Terrance Lam is out in Science Signaling today. We investigated how #GPCR #signalling can accelerate invasion in TNBC.

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 😀🧪

Can you add me please?

Our latest study is now online at Science Advances! We report the structure of the gigantic TSC:WIPI3 complex revealing new insights into lysosomal docking and dysregulation in disease. #cryoEM #mTOR 🧪

Here we are at the start before we were covered in green and blue!

We had a great time yesterday at the Children's Tumour Foundation Australia Conquer #NF in Colour event in Melbourne. It was great to join so many others in supporting the important work of #CTFAustralia, who advocate for and support the 1:3000 people who are diagnosed NF.
