The family of mammalian fatty acid–binding proteins (FABPs). (a) Superimposition of crystal structures of unliganded FABP1–9 generated in PyMOL (FABP1, 2F73; FABP2, 1IFC; FABP3, 6AQ1; FABP4, 3RZY; FABP5, 4LKP; FABP6, 5L8I; FABP7, 1FDQ; FABP8, 3NR3; and FABP9, 4A60). Panel adapted from Reference 119 with permission from Elsevier. (b) Table listing the mammalian FABPs, whose numbers reflect the order of their initial discovery.
