Fatty acid binding proteins (FABPs) are intracellular proteins and exhibit high affinity for small lipophilic ligands. FABP-3 is expressed in the skeletal muscle, heart, brain and brown adipose tissue. And its expression in skeletal muscles is elevated on consumption of a high fat diet. The gene encoding it is localized on human chromosome 1p35.
FABP3 is a newly introduced plasma marker of acute myocardial infarction (AMI). FABP3 is identified as a novel selective autophagy substrate of OPTN (optineurin, a macroautophagy/autophagy receptor, is found to play a pivotal role in selective autophagy, coupling autophagy with bone metabolism). FABP3 promotes adipogenesis and inhibits osteogenesis of MSCs. Knockdown of FABP3 alleviates bone loss in optn-/ - mice and aged mice[1][2].
