FABP1 (rat recombinant) Cayman Chemical Item Number 10005200 Description Source:recombinant N-terminal hexahistidine-tagged protein expressed in E. coli · Mr:18.3 kDa · Protein concentration:0.5 mg/ml · Fatty acid binding protein 1 (FABP1) is one of nine known cytosolic FABPs ranging in size from 14-15 kDa containing 127-132 amino acids.1↗ FABP1 is composed of ten antiparallel β strands that form a barrel with a bigger binding pocket than the other FABPs allowing it to accommodate two fatty acids. Expression of FABP1 is decreased in hepatoblastoma and hepatocellular carcinoma making the protein a potential tumor marker. Moreover, studies have suggested FABP1 as a potential biomarker for both liver and kidney injury.1↗ Cayman’s FABP1 has been functionally characterized by a fluorescence displacement assay using the fluorescent fatty acid analogue 11-(dansyl amino)undecanoic acid (DAUDA). Both arachidonic acid and oleic acid effectively displace DAUDA from the FABP binding pocket in a concentration-dependent manner.
