Diazepam binding inhibitor
Diazepam Binding Inhibitor (DBI) is a protein that in humans is encoded by the DBI gene. It is also known as acyl-CoA binding protein (ACBP), which has a high affinity for diazepam.
Function[edit | edit source]
DBI is a protein that is expressed in the brain and other tissues. It has been found to inhibit the binding of diazepam to the GABA_A receptor, hence its name. It is also known to have a role in the regulation of lipid metabolism, acting as an intracellular carrier of acyl-CoA esters.
Structure[edit | edit source]
The DBI protein is a small 10kDa protein that is highly conserved across species. It consists of a single polypeptide chain of 86 amino acids. The structure of DBI is characterized by a large hydrophobic pocket that is capable of binding to acyl-CoA esters.
Clinical significance[edit | edit source]
DBI has been implicated in several neurological disorders, including anxiety disorders, schizophrenia, and epilepsy. It has also been associated with metabolic syndrome, due to its role in lipid metabolism.
