Wdr45 Wd Repeat Domain 45 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
WDR45 encodes a WD repeat protein involved in autophagy and early iron metabolism. Mutations cause a form of neurodegeneration with brain iron accumulation (NBIA) characterized by progressive neurological deficits.
WDR45 (also called WIPR1) participates in autophagy:
The protein contains WD40 repeats that form a beta-propeller structure.
WDR45 mutations cause X-linked NBIA:
Static Encephalopathy of Childhood with Neurodegeneration in Adulthood:
WDR45 variants have been reported in Rett-like syndrome:
WDR45 is expressed in neuronal tissues:
Cytoplasmic and punctate staining pattern consistent with autophagosomal localization.
| Strategy | Approach | Status |
