Fatty Acid Binding Protein 1 (FABP-1) also known as Liver-type fatty acid-binding protein (L-FABP) is a small protein with a molecular weight of approximately 14 kDa. FABP-1 is abundantly expressed in the liver and also found in the intestine and kidneys. It functions by binding long-chain fatty acids and other lipophilic substances facilitating their transport within cells. The protein aids intracellular lipid trafficking assisting in the storage and metabolism of fatty acids.

Biological function summary

FABP-1 assists cells in maintaining lipid homeostasis by transporting these fatty acids to different cellular compartments for oxidation signaling or storage. It does not form part of a complex but independently interacts with lipids to buffer their concentration within the cytoplasm. Its role in lipid transport is essential for maintaining metabolic balance and energy production.

Pathways

FABP-1 participates in key metabolic pathways specifically the lipid metabolism and peroxisome proliferator-activated receptor (PPAR) signaling pathway. These pathways influence energy homeostasis and lipid modulation within cells. FABP-1 interacts with other proteins such as peroxisome proliferator-activated receptor alpha (PPARα) which regulates the expression of genes involved in lipid metabolic processes.

FABP-1 shows connections to liver conditions and metabolic syndrome. Altered levels of FABP-1 can indicate liver injury and could be used as a biomarker for non-alcoholic fatty liver disease (NAFLD). FABP-1 also connects to apolipoprotein E (ApoE) a protein involved in lipid metabolism in relation to the development and progression of atherosclerosis impacting cardiovascular health.
