SEQUENCE SIMILARITIES

Belongs to the TspO/BZRP family.

TISSUE SPECIFICITY

Found in many tissue types. Expressed at the highest levels under normal conditions in tissues that synthesize steroids.

SUBCELLULAR LOCATION

Mitochondrion membrane, cytosol.

FUNCTION

Present mainly in the mitochondrial compartment of peripheral tissues, the protein encoded by this gene interacts with some benzodiazepines and has different affinities than its endogenous counterpart. Can bind protoporphyrin IX and may play a role in the transport of porphyrins and heme. 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. Alternatively spliced transcript variants have been reported; one of the variants lacks an internal exon and is considered non-coding, and the other variants encode the same protein.
