The LMB recently hosted a symposium to mark 50 years since Richard Henderson and Nigel Unwin published the structure of bacteriorhodopsin, the first 3D structure of a protein determined by #cryoEM.

In-cell structure of a LINC complex reveals the molecular basis for membrane remodelling and head-to-tail coupling in sperm cells In eukaryotic cells, LINC complexes physically bridge the two nuclear membranes to cytoskeletal filaments, transmitting mechanical forces to the nucleus. Due to their dynamic and membrane-embedded nat...

Excited to share our latest work! We found transcription factor SPT6 and phosphorylated Pol II CTD help recruit U1 snRNP to elongating Pol II, allowing efficient co-transcriptional splicing.

Glad to be featured in the Editors’ Highlights!

Cryo-EM structure of human telomerase dimer reveals H/ACA RNP-mediated dimerization Telomerase ribonucleoprotein (RNP) synthesizes telomeric repeats at chromosome ends using a telomerase reverse transcriptase (TERT) and a telomerase RNA (hTR in humans). Previous structural work showe...

Proud to share our work where we resolved a longstanding question regarding the existence of a human telomerase dimer and provided insights into its function. Led by 3 amazing lab members in collaboration with @yiliangding.bsky.social and @rdaslab.bsky.social.

🚨 New preprint!
Using U-ExM + in situ cryo-ET, we show how C2CD3 builds an in-to-out radial architecture connecting the distal centriole lumen to its appendages. Great collab with @cellarchlab.com @chgenoud.bsky.social @stearnslab.bsky.social 🙌. #TeamTomo #UExM

Cryo-EM structure of the vault from human brain reveals symmetry mismatch at its caps The vault protein is expressed in most eukaryotic cells, where it is assembled on polyribosomes into large hollow barrel-shaped complexes. Despite its widespread and abundant presence in cells, the bi...

The amazing Sofia Lövestam initiated the below project, when she became interested in the vault particles that we sometimes observe in #cryoEM images of brain-derived #amyloid filaments.
www.biorxiv.org/content/10.1...

At left, a reconstruction of the vault cap with C39 symmetry imposed; at right, the reconstruction after identifying the correct symmetry, with the three non-equivalent protomers highlighted.

1/x New story - the structure of the Vault cap, at 2.3Å! Matching a beautiful preprint from @sjorsscheres.bsky.social, we show that the cap of the vault particle has C13 symmetry, in contrast to the 39-fold symmetry of the body. Study lead by talented postdoc @huanli00.bsky.social from my group! ⬇️

We have a preprint for you

EHD2 forms rings on caveolae necks, in contrast to most EHDs forming helices. We determined its structure on membranes and show that N-term acts as a spacer

Chemists recreate how RNA might have reproduced for first time Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life.

How did life on Earth begin? 🌍🧬
New #LMBResearch from Phil Holliger’s group, including James Attwater (now @uclchemistry.bsky.social‬‬ @uclnews.bsky.social) shows how pH-freeze-thaw cycles enables RNA self-replication, overcoming a key evolutionary hurdle.‬

Problem cryo-ET structure alert. A recent paper by Lange et al. in @natcellbio.nature.com (tinyurl.com/38s6a4dn) reported an unusual-looking model of the prohibitin complex in situ. We asked: how was this structure generated? Our reanalysis offers an explanation: tinyurl.com/mszdtwxx 🧵

In our latest preprint we used cryoEM to solve the structure of A-ENA fibers and show that they are stabilized by 10 isopeptide bonds per monomer. A-ENA couples the spore to the cry-toxins, and in doing so increases the virulence of Bacillus thuringiensis: www.researchsquare.com/article/rs-6...
