tinyurl.com/Raf1GLS We learn that Raf1 can be localized to the mitochondria and interact with GLS to regulate glutamine metabolism in cancer. A combination of cross-linking mass spec, AlphaFold predicted structures, and docking allowed us to identify and mutate the interaction interface.
Graphical abstract depicting Raf1 being translocated to the mitochondrial matrix where it regulates GLS tetramerization and activity. This is decoupled from its canonical MAPK activity.

Protein codes promote selective subcellular compartmentalization
Cells have evolved mechanisms to distribute ~10 billion protein molecules to subcellular compartments where diverse proteins involved in shared functions must assemble. Here, we demonstrate that prote...

Cancer cells often harbor oncogenes outside chromosomes on extrachromosomal DNA (ecDNA), which is unevenly inherited by dividing cells. We reported in Nature last week that collectives of ecDNAs are inherited together by dividing cancer cells. 1/ www.nature.com/articles/s41...

Too often we spend only two weeks choosing a problem and then many years trying solving it, but this limits our potential impact. A must read for PhD students: Problem choice and decision trees in science and engineering. pubmed.ncbi.nlm.nih.gov/38608651/

Decoding the epigenetics and chromatin loop dynamics of androgen receptor-mediated transcription - Nature Communications
Androgen receptor (AR) is the critical driver of nearly all prostate cancer. The authors show that AR activation causes specific pre-existing chromatin loops to increase contact frequency with target ...

Republicizing my preprint from earlier this year! We found that mitochondrial Raf1 upregulates glutamine catabolism in cancer cells. www.biorxiv.org/content/10.1...

Mitochondrial Raf1 Regulates Glutamine Catabolism
Raf1 is present within the mitochondrial matrix, where it binds GLS to regulate glutamine catabolism and tumorigenesis. In cancer, Raf1 activation occurs via mechanisms that include mutation of upstr...
