UMOD forms filaments that bind to uropathogenic bacteria, facilitating their aggregation and clearance from the urinary tract. Here, we present the cryo-electron microscopy (cryo-EM) structure of the bacteria-binding D10C domain of UMOD and reveal its binding to the filament core. The details of D10C-core binding explain the formation of distinct filament lattice architectures adopted by UMOD. The D10C-core binding interface gives rise to diverse filament lattice structures, ranging from open and expansive to compact and dense conformations, or a combination of both. We hypothesize that other molecules present in urine may act as cross-linking agents, further stabilizing this binding interface and facilitating the connection of individual filaments into larger networks capable of effectively trapping bacteria. Structural mapping of kidney disease-related mutations points toward the abolition of disulfide bonds and promotion of mutant UMOD aggregation. | |||||||||
