Happy New Year! (and first post here 😀) Excited to share the final version of our work where we combine deep mutational scanning, cryo-EM, and molecular dynamics to further resolve the mechanisms of pH sensing in GPCRs. 🧵(1/n) www.cell.com/cell/fulltex...

Very excited to share the first story from my postdoc where we uncover the structural basis for slow Cas9 turnover! We use kinetics-guided cryo-EM to capture 25 conformational states of SpCas9 from a single dataset - including the first look at Cas9 releasing product. biorxiv.org/content/10.1...

We will be hosting 3rd Full Circle Symposium for Native Biologists hosted at UCSF in April 2025! We aim to build community and provide meaningful opportunities for Native scientists. If you are a Native biologist who is interested plz fill this out to stay up to date: forms.gle/AN7nfkhdB3Fv...

as a Big Nerd I have to tell you I went to Mendel’s abbey to look at his peas but the most notable part is actually the little hats he made for his microscopes

Do you know who Douglas Prasher is? Many don't, even though he is the person who cloned the original #GFP gene in the late 1980s. In my short history of plant light #microscopy I also cover a bit of his story - & why he is relatively unknown today, despite the importance of his work. See this 🧵👇

A certain researcher has had 3 papers retracted due to obvious manipulation as in this example below. Saying that scientists cannot push for retraction because a paper is already peer reviewed or should shut up as they never tried to republish something completely wrong is not a good look

I am already running a service to notify about new #SerialEM releases by email at nexperion.net/serialemupdatenotices, but considering to make this a Bluesky bot as well ... is this something the #teamtomo #cryoEM #cryoET community would be interested in?

I kind of forgot how to announce Feeds, but here goes For an all-in-one CryoEM Feed: #CryoEM, #CryoET, #TeamTomo all-in-one feed that curates posts from the last 7 days containing the various cryoEM and cryoET related hashtags and keywords. bsky.app/profile/did:...

Promiscuous G-protein activation by the calcium-sensing receptor - Nature

Structures of the human calcium-sensing receptor can be bound into complex with G proteins from three different Gα subtypes while maintaining G-protein-binding specificity.

Time-resolved cryo-EM of G-protein activation by a GPCR - Nature

Time-resolved cryo-EM is used to capture structural transitions during G-protein activation stimulated by a G-protein-coupled receptor.

This one is for the #cryoEM afficionados. Ten years ago tomorrow (March 14th, 2014), I was at the Tahoe symposium on cryoEM 3D image analysis (taking place again this year, starting today!) and attended a talk by Alberto Bartesaghi, then from NCI-NIH now Duke.
