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. The protein is a key factor in the flow of cholesterol into mitochondria to permit the initiation of steroid hormone synthesis. 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.

GeneCards Summary for TSPO Gene
TSPO (Translocator Protein) is a Protein Coding gene. Diseases associated with TSPO include Focal Epilepsy and Hepatic Encephalopathy. Among its related pathways are HTLV-I infection and Ca, cAMP and Lipid Signaling. GO annotations related to this gene include cholesterol binding and androgen binding. An important paralog of this gene is TSPO2.
UniProtKB/Swiss-Prot for TSPO Gene
Can bind protoporphyrin IX and may play a role in the transport of porphyrins and heme (By similarity). Promotes the transport of cholesterol across mitochondrial membranes and may play a role in lipid metabolism (PubMed:24814875), 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 (PubMed:1847678).
