RT   little brown bat, Myotis lucifugus.";
RL   Biochim. Biophys. Acta 1676:63-70(2004).
CC   -!- FUNCTION: FABP are thought to play a role in the intracellular
CC       transport of long-chain fatty acids and their acyl-CoA esters. FABPs
CC       are important elements related to the hibernating state in mammals.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- INDUCTION: Up-regulated during hibernation in brown adipose tissue and
CC       skeletal muscle compared with levels in euthermic bats.
CC   -!- DOMAIN: Forms a beta-barrel structure that accommodates the hydrophobic
CC       ligand in its interior. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the calycin superfamily. Fatty-acid binding
CC       protein (FABP) family. {ECO:0000305}.
