Excited to have been able to collaborate with @labfriedman.bsky.social on this exciting new study that uncovers a new layer of regulation for BNIP3 and NIX!

New preprint from our lab! We uncover how a subset of mitophagy proteins BNIP3 and NIX are repressed and protected from turnover, we think so that they can perform a surveillance role to detect mitochondrial dysfunction under basal conditions. t.co/4XKkd4LsFi

Does anyone have a favorite mNeonGreen antibody that works well for western and IPs?

Finally, we find that presequence strength influences yeast metabolism in a model of COX4 deletion. When fused to a leaderless COX4, only presequences that promote “strong” import behavior restore respiratory growth to wild-type levels. 8/n

Mitochondrial presequences harbor variable strengths to maintain organellar function

Hundreds of mitochondrial-destined proteins rely on N-terminal presequences for organellar targeting and import. While generally described as positively charged amphipathic helices, presequences lack ...

This is a very sad day. Shock, despair, disappointment, disbelief... These only scratch the surface in describing this decision and how I feel. I began my career in Parkinson's research in Richard's lab. What happens now to all the trainees still there?

I’m ultra excited about our preprints on mitochondrial pearling. In two concurrent collaborative studies with @wallaceucsf.bsky.social, we investigated its consequences on mtDNA nucleoids (led by @jclandoni.bsky.social) & its biophysical causes (led by @gavsturm.bsky.social).
