Cryo-EM of mammalian PA28αβ-iCP immunoproteasome reveals a distinct mechanism of proteasome activation by PA28αβ
The proteasome activator PA28αβ affects MHC class I antigen presentation by associating with immunoproteasome core particles (iCPs). Cryo-EM structures of the mammalian PA28αβ -iCP immunoproteasome and free iCP, combined with cross-linking data, reveal the complex architecture and suggest a distinct...
