Acyl-CoA-binding protein (DBI)

Binds medium- and long-chain acyl-CoA esters with very high affinity and may function as an intracellular carrier of acyl-CoA esters. It is also able to displace diazepam from the benzodiazepine (BZD) recognition site located on the GABA type A receptor.

It is thus possible that this protein also acts as a neuropeptide to modulate the activity of the GABA receptor. .
