Integrative structural analysis of human endosomal NHE6 reveals a lipid-associated gate and disordered C-terminus - Nature Communications
The endosomal Na+ /H+ exchanger HsNHE6 regulates organellar pH and is implicated in neurological disease. Here the authors determine its cryo-EM structure and show a kinetic preference for K+ over Na+ transport.

Happy to see our NHE6 story published today in @natcomms.nature.com! Led by @lukasfeilen.bsky.social we reveal the #cryoEM structure, ion selectivity and regulation of the endosomal Na+/H+ exchanger NHE6, providing a framework for understanding Christianson syndrome. www.nature.com/articles/s41...

Our paper on the human endosomal Na⁺/H⁺ exchanger NHE6 (SLC9A6) is out in @natcomms.nature.com! We determined its cryo-EM structure at 3.4 Å, show a kinetic preference for K⁺ over Na⁺, and describe a lipid-associated gate and an intrinsically disordered C-terminus. www.nature.com/articles/s41...

Our paper on the human carnitine transporter OCTN2 (SLC22A5) is out in @natcomms.nature.com! We solved structures of OCTN2 in multiple states and explored how carnitine transport is Na⁺-dependent, providing a framework for understanding SPCD disease causing variants and drug interactions.

I am excited to share our latest preprint presenting the structure of human NHE6, a key endosomal Na⁺/H⁺ exchanger involved in Christianson syndrome. We bring together #cryo-EM, NMR, SAXS, lipidomics, and functional assays for an integrative analysis of NHE6 architecture, function, and regulation.

Structural insights into allosteric mechanism of glycine transporter-mediated analgesia
Chronic neuropathic pain, caused by nerve damage or disease, affects 10% of the population with rising incidence. The burden is exacerbated by ineffective treatments and overreliance on opioids. Neuro...
