The function of TSPO2 (translocator protein 2, Ensembl gene identifier ENSG00000112212) is as follows. Cholesterol-binding protein involved in the redistribution of cholesterol from lipid droplets to the endoplasmic reticulum (PubMed:19729679). Required to meet cholesterol demands during erythropoietic differentiation (PubMed:19729679). May play a role in transport processes at the plasma membrane of erythrocytes, including regulating VDAC-mediated ATP export, and import of the heme precursors protoporphyrin IX and 5-aminolevulinic acid (PubMed:27641616, PubMed:30061676, PubMed:31989647). {ECO:0000269|PubMed:19729679, ECO:0000269|PubMed:27641616, ECO:0000269|PubMed:30061676, ECO:0000269|PubMed:31989647}.
