π CryoSPARC v5.0 BETA is here!
Weβre excited to deploy another major #CryoSPARC release to help enable and accelerate #cryoEM data analysis. v5 has a redesigned underlying software system and many new features - highlights in thread!
Full changelog: cryosparc.com/updates/v5.0.0

Something really cool happened to me this year!
@HRBridges re-processed a #cryoEM dataset from some previous work of mine and colleagues (publicly available as EMPIAR-10739; see quoted post below for a summary of this work). She [β¦]

ALC1 Finds a New Foothold on the Nucleosome's Super-Groove https://www.biorxiv.org/content/10.1101/2025.11.10.687450v1
On a gruelling hunt for rare associated molecules in your #cryoEM particle stack and not sure where to look?
Discover practical tips and tricks in our new case study using #CryoSPARC v4.7.1 where we find and refine a low-population interaction partner!

π Introducing fully automated data processing for repeat-target #cryoEM.
Using new tools in #CryoSPARC, it is now possible to obtain resolutions & map quality equal to or better than manual processing, with zero user intervention.
Preprint: www.biorxiv.org/content/10.1...
Advanced #cryoEM workflows are easy in #CryoSPARC: use the Low-Level Results Interface to combine upstream extracted particles with downstream pose and CTF information, use a volume result from an intermediate iteration of a refinement to create a mask, and more! guide.cryosparc.com/application-...
Flexibility can be frustrating when processing a #cryoEM dataset. If your target has a wobbly domain, check out our new case study on FaNaC1 for continuous heterogeneity tips in #CryoSPARC!

Characterised members of the human SLC25 mitochondrial family. Members of the mitochondrial carriers are shown in rainbow (blue to red) cartoon and surface representations with their primary substrates shown in sphere representations to scale. Only one paralogue is shown.
Our review on the peculiar properties of mitochondrial carriers of the SLC25 family out: portlandpress.com/biochemj/art...
That's a wrap! The results of the first #cryoEM heterogeneity challenge are up on biorxiv!

When particles have orientation bias, the resulting maps are often streaked along the missing directions. In this case study, we cover why orientation bias produces anisotropic #cryoEM maps and how you may be able to recover from it!

A really insightful piece, Christian :) I used to think on this topic often. It will be interesting to see how things change for individuals and for the system, as more people realise the toll that such professional and personal dissonance can have.
I'd like to share this short piece on a topic I hope you will find useful. It is the result of a personl journey and many discussions with friends and peers. Let me know your thoughts.

Finally out! Working with this team was a fantastic learning experience. Also I was excited to determine the in situ clathrin structure for this project! Thatβs my first EM-structure upload to EMDB. Can I tell my mom I am a structural biologist now? π #cryoET
Using 33 pathogenic variants of citrin we identify crucial elements of the carrier domain required for transport and show that the N-terminal domain is not involved in calcium regulation of transport, but causes a mitochondrial import defect, when mutated.

A (hopefully) broadly-accessible tutorial below β¬οΈ (it ended up being really long!)
Cryo-EM map and atomic model of the RAVE complex (regulator of ATPases of endosomes and vacuoles) bound to a partial V1-ATPase complex
Atomic model showing that the RAVE complex binds to a region of the V1 complex subunit A not found in the homologous ATP synthase subunit beta.
Most protein complexes are born only once. V-ATPase assembles over and over as part of its regulatory mechanism, enabled by RAVE (regulator of ATPase of vacuoles and endosomes)
@hanlinw222.bsky.social's 1st struct of RAVE bound to a partial V1 complex now out in PNAS.
