ABCF3 (ATP-binding cassette sub-family F member 3) is an ABC transporter family member encoded by the ABCF3 gene in humans (UniProt: Q9NUQ8). The protein displays an antiviral effect against flaviviruses such as West Nile virus in the presence of OAS1B, suggesting a role in innate immune defense mechanisms.
ABCF3 is a 709 amino acid protein with a molecular mass of approximately 79.7 kDa. No specific tissue localization or canonical disease associations are documented in UniProt, though the antiviral function implicates potential relevance to neuroinflammatory pathways.
ABCF3 is down-regulated in Alzheimer's Disease brain tissue compared to age-matched controls (Chaparral AD proteomics). Analysis of post-mortem AD brain across four subcellular fractions using TMT-labeled quantitative proteomics showed a mean log2 fold-change of −0.3165, indicating modest reduction. This decreased expression may reflect altered innate immune responses or metabolic changes associated with AD pathology.
