Function

[TSPO_RHOSH] May play a role in the transmembrane transport of tetrapyrroles and similar compounds, and thereby contribute to the regulation of tetrapyrrole biosynthesis (PubMed:10409680). Binds tetrapyrroles and promotes the photooxidative degradation of protoporphyrin IX (PubMed:23651039). Binds protoporphyrin IX, hemin, and coproporphyrin III, but does not bind delta-aminolevulinic acid (PubMed:23952237, PubMed:20541505, PubMed:25635101). Can bind bilirubin, curcumin, gossypol, retinoic acid, cholesterol and the benzodiazepine receptor agonist PK-11195 (in vitro) (PubMed:23952237, PubMed:25635101). Plays a role in the response to low oxygen levels and in the regulation of the biosynthesis of photosynthetic pigments (PubMed:7673149, PubMed:10409680, PubMed:10681549).^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7]

Publication Abstract from PubMed

Wang comments that the diffraction data for the structure of the A139T mutant of translocator protein TSPO from Rhodobacter sphaeroides should be used to 1.65 instead of 1.8 angstroms and that the density interpreted as porphyrin and monoolein is better fitted as polyethylene glycol. Although different practices of data processing exist, in this case they do not substantially influence the final map. Additional data are presented supporting the fit of a porphyrin and monooleins.
