Nearly two decades after augmin's discovery in Drosophila, we have reconstituted the microtubule-binding region of the Drosophila augmin complex on microtubules and demonstrate the conserved mechanism by which augmin subunit HAUS6 orients augmin for microtubule branching.

We are excited to share our latest work elucidating the structural basis for how augmin binds to microtubules. Out just now @natcomms.nature.com :

Conserved function of the HAUS6 calponin homology domain in anchoring augmin for microtubule branching - Nature Communications
Augmin is essential for microtubule nucleation during cell division. This study reveals how the conserved calponin homology domain of the augmin subunit HAUS6 binds to microtubules to orient augmin fo...

Out just now @naturecomms.bsky.social: using cryo-EM and cryo-electron tomography, we provide evidence that structurally heterogeneous ribosomes can cooperate in protein synthesis in bacterial cells:

Cells can simultaneously produce structurally dissimilar ribosomes, suggesting functional specialization of distinct ribosome populations. Here, the authors show that distinct ribosomes cooperate rath...

Here we unexpectedly find that the ribosomal protein S20/L26—identified at the dawn of ribosome research but later deemed a biochemical artifact—is indeed a genuine component of the large ribosomal subunit. More on this ribosome content variation is here: www.nature.com/articles/s41...

Online today at @naturecomms.bsky.social and a great opportunity for our first post @bsky.app: in a major team effort, we reveal the structural mechanisms for centrosomal recruitment and organization of the human microtubule nucleator γ-TuRC: www.nature.com/articles/s41...
Structural mechanisms for centrosomal recruitment and organization of the microtubule nucleator γ-TuRC - Nature Communications
The γ-TuRC plays a central role for nucleation of microtubules at the centrosome. Here, the authors dissect structural mechanisms for centrosomal recruitment and regulation of the γ-TuRC and identify ...
