🥳 Our new paper on C2CD3 is out in @plosbiology.org With the labs of @cellarchlab.com , @chgenoud.bsky.social , and @stearnslab.bsky.social , we revealed the mammalian centriole Distal Ring architecture by combining #UExM and in situ #CryoET. Big congrats to @ebertiaux.bsky.social and all involved.

How does C2CD3 contribute to distal appendage formation in centrioles? @centriolelab.bsky.social show that C2CD3 acts as a central architectural organizer of the distal #centriole, bridging the luminal distal ring complex & peripheral appendage sites @plosbiology.org 🧪 plos.io/496XZuH

C2CD3 localizes to a ring structure observed in the lumen of the distal centriole by in situ cryo-electron tomography. Top: Confocal image of an expanded mouse photoreceptor cell immunolabeled for tubulin (magenta) and C2CD3 (green). DC, daughter centriole; BB, basal body; TZ, transition zone; CC, connecting cilium. Scale bar: 500 nm. Middle: In situ cryo-tomogram slices taken along the longitudinal axis of the centriole and connecting cilium. White arrowheads indicate microtubule triplets, black arrowheads indicate microtubule doublets, orange arrowheads mark the luminal ring structure, and yellow highlights the membrane. Scale bar: 50 nm. Bottom:  Model of the architecture of the distal region of the human centriole.

It was a lot of fun to write this review on cilia proteimics with Bernhard Schermer @cilib.social.cologne.ap.brid.gy and Ronald Ropeman, and we are excited to see it published in the @jcellsci.bsky.social special issue on Cilia and Flagella: from basic Biology to Disease.

📣 Here it is — our overview on ciliary proteomics! Great discussions and writing with @mick-lab.bsky.social and Ronald Roepman 🙏🙏 Hope we didn’t miss anything important - apologies if we did! #cilia #ciliopathies #proteomics @theracilproject.bsky.social @for5547.bsky.social tinyurl.com/yc8ztn5v

While trying to steer clear of the ‘best organelle’ debate, we’re delighted to highlight #JCSciliaSI, guest edited by @cilialab.bsky.social & @lottepedersen.bsky.social. And, we hope that even the most ardent fans of other organelles can agree that cilia are certainly beautiful to image!

We are thrilled to see this out in @jcellsci.bsky.social an in the special issue on Cilia. Cfap298 - which we call Kurly - is the mutant that keeps on giving us surprises! In this paper, a mutation generated by CRISPR, that deletes two aa and changes a third, specifically affects cilia motility.

Marvin Cortez, Cullen Young, Rebecca Burdine @rburdine1.bsky.social and colleagues identify a conserved domain in Cfap298 that governs left–right symmetry breaking in vertebrates. #JCSciliaSI journals.biologists.com/jcs/article/...
