Overlay histogram showing HeLa cells stained with ab199779 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab199779, 1/500 dilution) for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG [EPR25A] Alexa Fluor® 488 (ab199091) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HeLa cells fixed with 4% formaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Supplementary information

PBR also known as the Peripheral Benzodiazepine Receptor is a protein predominantly found in the outer mitochondrial membrane. It has alternate names like Translocator Protein (TSPO) and the mass of this protein is approximately 18 kDa. PBR is expressed in various tissues but shows high levels in steroidogenic tissues like adrenal glands as well as in the brain heart liver and kidneys. The abundant presence in these tissues highlights its importance in a variety of physiological functions.
Biological function summary

PBR interacts with cholesterol for the synthesis of steroid hormones making it important for steroidogenesis. PBR is a part of the Mitochondrial Permeability Transition Pore complex (MPTP) involved in regulating the transport of molecules across the mitochondrial membrane. Through its association with the MPTP PBR plays a significant role in mitochondrial functions such as apoptosis and energy metabolism. The interaction with other molecules also includes the binding with benzodiazepines impacting processes like immune response and cell proliferation.

Pathways

PBR plays a role in the steroid biosynthesis and apoptosis pathways. It interfaces with the StAR (Steroidogenic Acute Regulatory) protein to facilitate cholesterol transport into mitochondria the initial step in steroid hormone production. PBR is also involved in pathways that regulate apoptosis and mitochondrial function linking it to different cellular processes through interactions with proteins like VDAC (Voltage-Dependent Anion Channel).

PBR has relevance to conditions such as neurodegenerative diseases and cancer. PBR expression changes in disorders like Alzheimer's disease where it might reflect mitochondrial dysfunctions. It has also been associated with certain cancers where aberrant PBR activity might contribute to altered cell proliferation and apoptosis. Proteins like caspases are involved in the apoptotic pathways connected with PBR highlighting its involvement in disease processes.

Target data

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).
