Purity > 90% as determined by SDS-PAGE. MW: 15.7kDa. Full Length of Mature Protein of Isoform 2: 2-104aa. N-terminal 6xHis-tagged. Homo sapiens (Human). 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 therefore possible that this protein also acts as a neuropeptide to modulate the action of the GABA receptor.
