    The plasma membrane Ca2+ ATPase (PMCA) is essential for maintaining Ca2+ homeostasis in eukaryotic cells, and neuroplastin (NPTN) was recently identified as an obligatory subunit of PMCA. Here the authors present the cryo-EM structure of NPTN bound to human PMCA1, which reveals that the NPTN transmembrane (TM) helix interacts with TM10 and the TM8-9-linker of PMCA1
