Structural biology of the PCI-protein fold.

ABSTRACT: The PCI fold is based on a stack of α-helices topped with a winged-helix domain and is found in a range of proteins that form central parts of large complexes such as the proteasome lid, the COP9 signalosome, elongation factor eIF3, and the TREX-2 complex. Recent structural determinations have given intriguing insight into how these folds function both to facilitate the generation of larger proteinaceous assembles and also to interact functionally with nucleic acids.
