WDR73 is a WD40 domain containing protein important in protein complex scaffolding. The gene is notably expressed in the kidney (podocytes and tubules) and in various neuronal cell types in the brain as well as cerebral endothelial cells. WDR73 functional studies indicate that it is important in microtubule function. Homozygous mutations in WDR73 have been associated with Galloway-Mowat Syndrome 1.
