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. It is thought that FABPs roles include fatty acid uptake, transport, and metabolism.[2]
The phytocannabinoids (THC and CBD) inhibit endocannabinoidanandamide (AEA) uptake by targeting FABP5, and competition for FABPs may in part or wholly explain the increased circulating levels of endocannabinoids reported after consumption of cannabinoids.[3] Results show that cannabinoids inhibit keratinocyteproliferation, and therefore support a potential role for cannabinoids in the treatment of psoriasis.[4]
