Supplementary information

The FABP5 protein also known as Fatty Acid Binding Protein 5 or Epidermal-type Fatty Acid Binding Protein (E-FABP) serves an important role in the transport and metabolism of long-chain fatty acids. It has a molecular mass of approximately 15 kDa. FABP5 is expressed in multiple tissues with notably high expression in the epidermis brain liver and adipose tissue. This protein assists in intracellular fatty acid movement affecting cellular lipid catabolism.
Biological function summary

FABP5 interacts with specific ligands such as long-chain fatty acids which influences cellular processes like growth differentiation and energy homeostasis. It is not known to be part of a larger complex. This protein is integral in regulating lipid signaling pathways and responses due to its binding capacity which modulates the availability of fatty acids for metabolic processes. Its expression pattern hints at a possible role in the body's adaptation to dietary lipid intake.

Pathways

FABP5 holds a significant position in the peroxisome proliferator-activated receptor (PPAR) signaling pathway and the fatty acid metabolism pathway. In the PPAR signaling pathway FABP5 influences the activity of PPARβ/δ receptors which regulate gene expression involved in lipid metabolism and energy homeostasis. It is related to other fatty acid binding proteins such as FABP4 which similarly participate in lipid metabolic processes and have roles in the regulation of lipid and glucose metabolism.

Researchers have linked FABP5 to conditions like psoriasis and type 2 diabetes. In psoriasis the overexpression of FABP5 has been observed in skin lesions suggesting that it might contribute to the pathological process. FABP5 is also connected to metabolic syndrome and insulin resistance as its dysregulation can influence lipid and glucose metabolism processes. In these disorders FABP5 interacts with proteins like PPARγ indicating possible intervention points for therapeutic targeting.

Target data

Intracellular carrier for long-chain fatty acids and related active lipids, such as endocannabinoids, that regulate the metabolism and actions of the ligands they bind. In addition to the cytosolic transport, selectively delivers specific fatty acids from the cytosol to the nucleus, wherein they activate nuclear receptors (PubMed : 21395585, PubMed : 22170058). Delivers retinoic acid to the nuclear receptor peroxisome proliferator-activated receptor delta; which promotes proliferation and survival. May also serve as a synaptic carrier of endocannabinoid at central synapses and thus controls retrograde endocannabinoid signaling. Modulates inflammation by regulating PTGES induction via NF-kappa-B activation, and prostaglandin E2 (PGE2) biosynthesis during inflammation (By similarity). May be involved in keratinocyte differentiation (PubMed : 8092987).
