Three-dimensional interplay among the ligand-binding domains of the urokinase-plasminogen-activator-receptor-associated protein, Endo180.

Endo180, also known as the urokinase plasminogen activator receptor (uPAR)-associated protein (uPARAP), is one of the four members of the mannose receptor family, and is implicated in extracellular-matrix remodelling through its interactions with collagens, sugars and uPAR. The extracellular portion of Endo180 contains an amino-terminal cysteine-rich domain, a single fibronectin type II domain and eight C-type lectin-like domains. We have purified a soluble version of Endo180 and analysed it by single-particle electron microscopy to obtain a three-dimensional structure of the N-terminal part of the protein at a resolution of 17 A and reveal, for the first time, the interactions between non-adjacent domains in the mannose receptor family. We show that for Endo180, the cysteine-rich domain contacts the second C-type lectin-like domain, thus providing structural insight into how modulation of its several ligand interactions may regulate Endo180 receptor function.[1]
