Identification, biochemical characterization and crystallization of the central region of human ATG16L1.

ABSTRACT: ATG16L1 plays a major role in autophagy. It acts as a molecular scaffold which mediates protein-protein interactions essential for autophagosome formation. The ATG12~ATG5-ATG16L1 complex is one of the key complexes involved in autophagosome formation. Human ATG16L1 comprises 607 amino acids with three functional domains named ATG5BD, CCD and WD40, where the C-terminal WD40 domain represents approximately 50% of the full-length protein. Previously, structures of the C-terminal WD40 domain of human ATG16L1 as well as of human ATG12~ATG5 in complex with the ATG5BD of ATG16L1 have been reported. However, apart from the ATG5BD, no structural information for the N-terminal half, including the CCD, of human ATG16L1 is available. In this study, the authors aimed to structurally characterize the N-
