VAT1 (Vesicle-associated membrane protein-associated protein A) is a conserved eukaryotic protein primarily localized to mitochondrial membranes and synaptic vesicles. It belongs to the quinone oxidoreductase subfamily and features a Rossmann-fold structure that facilitates NADPH binding. First identified in neurotransmitter release regulation, VAT1 is now recognized for broader roles in vesicle trafficking, mitochondrial dynamics, and cellular energy metabolism. Its interaction with cytoskeletal components and membrane fusion machinery underscores involvement in cell motility, organelle morphology, and apoptosis regulation.
Recombinant VAT1 protein production typically employs E. coli or mammalian expression systems, enabling structural and functional studies. The purified protein has been instrumental in crystallographic analyses revealing its unique dimeric configuration and redox-sensitive cysteine residues. Researchers utilize VAT1 recombinant proteins to investigate mitochondrial dysfunction mechanisms in neurodegenerative diseases, given its altered expression patterns in Alzheimer's and Parkinson's models. In cancer biology, VAT1 overexpression correlates with tumor metastasis, driving interest in its potential as a therapeutic target. Current applications include drug screening platforms and antibody development against its extracellular epitopes observed in certain malignancies. Recent studies also explore VAT1's role in viral infection pathways through host membrane remodeling interactions. Despite progress, the full scope of its molecular interactions and tissue-specific isoforms remains under active investigation.
