Dnajc13 Protein (Rme 8) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
DNAJC13 (also known as RME-8) is a J-domain containing protein that functions in endosomal trafficking. It plays important roles in protein sorting through the endosomal system and has been implicated in Parkinson's disease.
DNAJC13 contains:
DNAJC13/RME-8 is involved in endosomal trafficking:
DNAJC13 mutations cause autosomal dominant PD:
DNAJC13 variants may modify DLB risk:
DNAJC13 has been implicated in essential tremor.
