    Na+/H+ exchangers (NHEs) are ancient membrane-bound nanoma- chines that work to regulate intracellular pH, sodium levels and cell volume. NHE activities contribute to the control of the cell cycle, cell proliferation, cell migration and vesicle trafficking. NHE dysfunction has been linked to many diseases, and they are targets of pharma- ceutical drugs. Despite their fundamental importance to cell home- ostasis and human physiology, structural information for the mammalian NHEs was lacking. Here, we report the cryogenic elec- tron microscopy structure of NHE isoform 9 (SLC9A9) from Equus caballus at 3.2 Å resolution, an endosomal isoform highly expressed in the brain and associated with autism spectrum (ASD) and atten- tion deficit hyperactivity (ADHD) disorders. Despite low sequence identity, the NHE9 architecture and ion-binding site are remarkably most similar to distantly related bacterial Na+/H+ antiporters with 13 transmembrane segments. Collectively, we reveal the conserved architecture of the NHE ion-binding site, their elevator-like structural transitions, the functional implications of autism disease mutations and the role of phosphoinositide lipids to promote homodimerization that, together, have important physiological ramifications.

    Here, we present a simple overexpression condition for high-throughput screening of membrane proteins in Escherichia coli. For the vast majority of bacterial membrane protein targets tested the MEMbrane protein Single shoT Amplification Recipe-MemStarleads to high production yields of target protein. The use of MemStar has facilitated structural studies of several transport proteins.
