Function
Promotes the transport of cholesterol across mitochondrial membranes and may play a role in lipid metabolism, but its precise physiological role is controversial. It is apparently not required for steroid hormone biosynthesis. Was initially identified as peripheral-type benzodiazepine receptor; can also bind isoquinoline carboxamides. Can bind protoporphyrin IX and may play a role in the transport of porphyrins and heme.
KEGG Pathway
Neuroactive ligand-receptor interaction (hsa04080 )
HTLV-I infection (hsa05166 )
Reactome Pathway
Pregnenolone biosynthesis (R-HSA-196108 )
