FIS1 is an essential component of the mitochondrial fission machinery[1:1][3]:
The FIS1 protein contains:
Mitochondrial fission is dysregulated in Alzheimer's disease[4][5]:
In Parkinson's disease, FIS1 contributes to dopaminergic neuron vulnerability[6][7]:
FIS1 plays a key role in mitophagy[8]:
| Interactor | Interaction Type | Functional Significance |
|---|---|---|
| DRP1 (DNM1L) | Recruitment | Mitochondrial fission GTPase |
| MFF | Co-receptor | Drp1 adaptor complex |
| PINK1 | Kinase | Parkin-dependent mitophagy |
| BAX | Pro-apoptotic | Mitochondrial apoptosis |
| TBC1D15 | GTPase-activating | Mitochondrial dynamics regulator |
FIS1 is expressed in neurons throughout the brain:
