== Publication Abstract from PubMed ==
 +
Infectious bacteria are cleared from mammalian cells by host autophagy in combination with other upstream cellular components, such as the autophagic receptor NDP52 and sugar receptor galectin-8. However, the detailed molecular basis of the interaction between these two receptors remains to be elucidated. Here, we report the biochemical characterization of both NDP52 and galectin-8 as well as the crystal structure of galectin-8 complexed with an NDP52 peptide. The unexpected observation of nicotinamide adenine dinucleotide located at the carbohydrate-binding site expands our knowledge of the sugar-binding specificity of galectin-8. The NDP52-galectin-8 complex structure explains the key determinants for recognition on both receptors and defines a special orientation of N- and C-terminal carbohydrate recognition domains of galectin-8. Dimeric NDP52 forms a ternary complex with two monomeric galectin-8 molecules as well as two LC3C molecules. These results lay the groundwork for understanding how host cells target bacterial pathogens for autophagy.
