== Publication Abstract from PubMed ==
The C-type lectin receptor Clec4f has been identified as a specific surface marker for Kupffer cells, although its ortholog is absent in humans and its biological function remains elusive. Here, we report the crystal structure of a truncated mouse trimeric Clec4f. The orientation between the carbohydrate-recognition domain of Clec4f and its neck region differs from other C-type lectins, resulting in an observed distance of 45 A between the glycan-binding sites within the Clec4f trimer. Interestingly, the trimeric coiled-coil interface within its heptad neck region contains multiple polyglutamine interactions instead of the predominantly hydrophobic leucine zipper found in other C-type lectin receptors. The Clec4f trimeric structure displays unique features regarding its assembly and ligand recognition, shedding light on the evolution and diversity of the C-type lectin family.
