Events celebrating women in electron microscopy are rare, which made my recent experience at the Ernst Ruska-Centre (ER-C), Forschungszentrum Jülich, Germany, truly special. I had the privilege of not only attending but also serving as a young keynote speaker at this inspiring gathering. 🎉

Lab’s 1st preprint!

Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate.

@cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation.

He is on the job market!

I’m thrilled to share my postdoc work and the first paper from the McKinley Lab! 🎉
@karalmckinley.bsky.social
We built the first transgenic model of menstruation in mice.
We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪

Induction of menstruation in mice reveals the regulation of menstrual shedding

During menstruation, an inner layer of the endometrium is selectively shed, while an outer, progenitor-containing layer is preserved to support repeated regeneration. Progress in understanding this co...

Curious to know how does auxiliary subunit Neto2 modulate kainate receptor (KAR) function? Read our latest study describing GluK2-Neto2 complex-captured in both its activated and true apo states.

Activation of kainate receptor GluK2–Neto2 complex - Nature Structural & Molecular Biology

Gangwar et al. present cryo-electron microscopy structures of GluK2 kainate receptors with auxiliary subunit Neto2 and reveal the basis of receptor activation.

Happy to share a new preprint from the Clarke & Vallese (@fravallese.bsky.social) labs reporting #cryoem structures of two RBC stomatin complexes – with AQP1 & UT-B - continuing the SPFH theme from our recent vault preprint! This was a fun one and has been cooking for a while - read on for more! ⬇️

Upper - cryo-EM reconstruction of stomatin AQP1 complex. Lower - reconstruction of stomatin-UT-B complex.

Have you published lipid-protein interactome data? Please let us know, we’d love to include it in the repository. The goal is to build a centralized hub for the scientific community.

Huge thanks to Gaelen Guzman, a graduate student/postdoc in the lab who built it from scratch.
