Background:
This gene encodes the fatty acid binding protein found in epidermal cells,and was first identified as being upregulated in psoriasis tissue. Fatty acid binding proteins are a family of small,highly conserved,cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. FABPs may play roles in fatty acid uptake,transport,and metabolism. Polymorphisms in this gene are associated with type 2 diabetes. The human genome contains many pseudogenes similar to this locus.
