Epg5 Gene Ectopic P Granules 5 Autophagy Tutor is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
EPG5 (Ectopic P-Granules 5 Autophagy Tutor) is a gene located on chromosome 18q12.3 that encodes a key autophagy protein. EPG5 plays a crucial role in late autophagy (the degradation of autophagosomes by lysosomes) and is essential for neuronal survival[1]. Mutations in EPG5 cause autosomal recessive hereditary spastic paraplegia (HSP) type 41 (SPG41) and are associated with Parkinson's disease[2][3].

EPG5 is a critical regulator of autophagy:
In neurons, EPG5 is essential for:
EPG5 mutations cause autosomal recessive SPG41[2:1]:
EPG5 variants may modify PD risk[3:1]:
