Mitochondrial Carrier Family is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The mitochondrial carrier family (SLC25) is a group of transport proteins located in the inner mitochondrial membrane. They facilitate the movement of metabolites, nucleotides, and other molecules across the mitochondrial membrane.
- Six transmembrane α-helices
- Three repeated motifs
- Carrier-specific substrate binding sites
- Symmetric trimeric arrangement
- Antiport (exchange transporters)
- Uniport (single substrate transporters)
- SLC25A1 (CIC): Citrate carrier
- SLC25A2 (AGC2): Aspartate-glutamate carrier
- SLC25A3 (PiC): Phosphate carrier
- SLC25A4 (AAC1): ADP/ATP translocase
- SLC25A4 (ANT1): ADP/ATP translocase 1
- SLC25A5 (ANT2): ADP/ATP translocase 2
- SLC25A6 (ANT3): ADP/ATP translocase 3
- SLC25A12 (AGC1): Arginine/glutamate carrier
- SLC25A13 (AGC2): Aspartate/glutamate carrier
- Import of ADP, phosphate
- Export of ATP
- Citrate shuttle for fatty acid synthesis
- Calcium handling
- Amino acid metabolism
- Nucleotide balance
- ANT1 mutations cause PEO
- Altered nucleotide transport in PD
- Impaired energy metabolism in AD
- Targeting mitochondrial carriers for neuroprotection
- Modulating metabolite exchange
- Gene therapy approaches
The study of Mitochondrial Carrier Family has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
