Drp1 Protein (Dynamin 1 Like Protein) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
DNM1L is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of DNM1L is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
Protein Name: DRP1 (Dynamin-1-Like Protein)
Gene: DNM1L
UniProt ID: O00429
Molecular Weight: 80 kDa
Subcellular Localization: Cytosol (main), recruited to mitochondrial outer membrane

DRP1 has a multidomain architecture:
Unlike typical dynamins, DRP1 lacks a membrane-anchoring domain and is recruited to mitochondria via adaptor proteins[1].
DRP1 executes mitochondrial division:
DRP1 also mediates peroxisome division:
Proper fission supports:
DRP1 hyperactivation in AD:
In PD, DRP1 plays complex roles:
