In the Abstract of this Article, the sentence ‘Here we present a near full-length structure of the GABAB receptor at atomic resolution, captured in an inactive state by cryo-electron microscopy’ should have been ‘Here we present a near full-length structure of the GABAB receptor, captured in an inactive state by cryo-electron microscopy’. The original Article has been corrected online.
