Australian Grant assessors- can we please stop adding useless comments like ‘‘big papers from post doc in established international lab but has not proven themselves here yet”. It’s REALLY hard to move countries, set up an independent team, and produce high impact work in under 3 years.

Day 5 @olibclarke.bsky.social did double duty talking about model building & validation and giving a Coot/chimeraX tutorial. Also Justin Flatt from the @rcsbpdb.bsky.social shared best practices for #cryoEM deposition & validation.

Why are biological membranes asymmetric, with different lipids in the two bilayer leaflets? Discovered in the 70s, lipid asymmetry is linked to many cellular processes, but why the cell needs it is largely unclear. @pavelbarahtjan.bsky.social addresses this question: www.biorxiv.org/content/10.1...

Session 9: Mitch O'Connell bacterial/bacteriophage arms race. Small RNAs to mount an adaptive MGE immune response. CRISPR RNA defence systems. How does Cas13 work as an enzyme to target RNA? Csx28 128 aa protein, TM, cyt. Co-opt membrane effectors? 👏 #LorneProteins2025
How does it enhance phage defence? Pfu/mL +/- Csx28. 10000x improvement in phage defence by small membrane protein. Bacterial growth with addition of phage. Bacteriostatic effect? Forms an octamerif forward in DDM, now nanodisc... ligand gating of channel? Depolarisation assay? Dye that is weakly fluorescent when cells are polarised, loss of polarisation increase fluor. DiBAC4. 40% depolarised with cas13b and csx28. No complex formation. Cleaved ssRNA to open this channel.

tRNA anticodon loop cleavage by target-activated CRISPR-Cas13a. Cleavage products from tRNAs. Pull down monomeric Csx28 no pulldown; Octomer- enrichment of ssRNA in pull-down. Pull downs on grids - 8 mol of tRNA degradation products bound to Csx28. Where is the tRNA cleaved? cmo5U? Xm5U? Keio collection - screened against tRNA modification enzyme kos. Modification of the wobble residue prevents the phage defence.

Csx27 4 TM protein next. Similar function to Csx28. Alphafold2 to identify similar RNA gated ion channels.

Session 10 Ibrahim Cissé-Super-res imaging of transcription. Cooperativity in weak & transient biological interactions. PolII clustering in a cell nucleus w STORM. Limitations for weak and transient interactions. Lightsheet microscopy to follow polymerase condensates & gene bursts #LorneProteins2025
High resolution in fixed cells, but temporal events - transient, sub diffraction clusters in live mammalian cells. -ve feedback - 4-5 polymerase load, clusters are released. Cells can hold clusters longer to increase transcriptional events. Dual colour super resolution. TcPALM. Measure active burst, estimate RNAs and correlate with cluster lifetime. Enhancer, mediator, PolII - Mediator and PolII in stem cells. Short lived 11 s. Subset large clusters 300-400 nm in size, long lived 10s of minutes. Lattice lightsheet. 3d, time lapse, 10s of minutes, a full nucleus every 15s or so.

Some clusters fuse to merge content. In vivo condensates with liquid like properties. Condensate proximity to Sox2 promoter correlates to mRNA burst intensity. Du et al, Cell, 2024.

Higher burst size, higher frequency of burst events. 1.5-2 fold higher proximal to a PolII condensate.

Anticorrelation between distance and burst size. When condensate contacts enhancer and generates. If superenhancer is distal from condensate, then no burst.

Mediator/PolII, Superenhancer DNA, nascent mRNA in 3 colours. Movie of condensate moving in to contact the superenhancer, Gene promoter active and mRNA increases. 

Is the condensate/superenhancer contact active? Yes, cohesion required to loop DNA - precise architecture of the DNA to achieve a burst. Cohesion loops DNA and stops at an enhancer element upstream of the promoter.

Lee et al 2024, Condensates - complex, liquid droplets? Proximity mini turbo ID? Accumulate any cargo of interest to be concentrated in the condensate. Turn on blue light and generate condensate localisation? Light induced targeting of endogenous condensates.

Cargo-miniturbo-ID-GFP blue light on, accumulates in condensate, biotinylation accumulating. LiTEC with BioID for proteomics on condensates. Some missing... Chimeric mining. Pass droplets through mass spec - often ignore low intensity peaks. Looked for background peaks. More to follow up..
