背景
-
Intestinal fatty acid-binding protein (FABP2) is a small cytoplasmic lipid-binding protein encoded by the FABP2 gene and predominantly expressed in absorptive epithelial cells of the small intestine. FABP2 Antibody / Intestinal Lipid Transport Marker is useful for studying enterocyte biology, dietary lipid absorption, epithelial differentiation, and intestinal metabolic regulation. FABP2 belongs to the fatty acid-binding protein family, a group of structurally related intracellular proteins that bind long-chain fatty acids and facilitate their intracellular trafficking and metabolic utilization.
FABP2 antibody, also referred to as Intestinal fatty acid-binding protein antibody or I-FABP antibody in the literature, recognizes a protein that plays a major role in intestinal lipid handling and nutrient absorption. FABP2 is localized primarily within the cytoplasm of mature enterocytes lining the small intestinal villi, where it participates in fatty acid uptake, intracellular transport, and delivery of lipids to pathways involved in triglyceride synthesis and energy metabolism. Due to its highly restricted intestinal expression pattern, FABP2 is widely used as a marker of differentiated intestinal epithelium and enterocyte maturation.
FABP2 contributes to intestinal metabolic homeostasis by binding dietary fatty acids and promoting their efficient intracellular movement following luminal absorption. The protein participates in pathways associated with lipid digestion, chylomicron assembly, cellular energy regulation, and epithelial barrier maintenance. FABP2 has also been investigated in obesity, insulin resistance, inflammatory bowel disease, intestinal injury, and metabolic syndrome, reflecting the importance of intestinal lipid metabolism in systemic metabolic health.
In histologic applications, FABP2 expression is commonly observed as strong cytoplasmic staining in absorptive epithelial cells of the small intestine, particularly within villous enterocytes. This characteristic localization pattern makes FABP2 a useful marker for intestinal epithelial differentiation and gastrointestinal tissue characterization. Changes in FABP2 expression have additionally been reported in gastrointestinal malignancies and inflammatory disorders affecting intestinal epithelial integrity and absorptive function.
FABP2 is encoded on human chromosome 4q28-q31 and produces a highly conserved beta-barrel fatty acid-binding protein typical of the FABP family. The compact ligand-binding structure enables rapid intracellular fatty acid exchange and transport within enterocytes exposed to fluctuating dietary lipid levels. FABP2 functions closely with other intestinal transport and metabolic proteins involved in nutrient sensing, fatty acid uptake, and epithelial metabolic adaptation.
Clone FABP2/6344 has been evaluated using western blotting, immunohistochemistry, and HuProt microarray specificity validation methods to support selective detection of FABP2 in research applications. Western blot analysis commonly demonstrates FABP2 near its predicted molecular weight in intestinal tissue lysates, while immunohistochemistry reveals strong enterocyte-associated cytoplasmic staining patterns consistent with the known biology of this intestinal lipid transport protein. Protein microarray validation further supports specificity for FABP2 among thousands of human proteins represented on the array.
