The encoded protein is involved in phosphate homeostasis by mediating phosphate export from the cell. Defects in this gene have been associated with idiopathic basal ganglia calcification-6. [provided by RefSeq, Jun 2016]. * **UniProt Summary**: Plays a role in phosphate homeostasis. Mediates phosphate export from the cell (PubMed:23791524, PubMed:25938945). Binds inositol hexakisphosphate (Ins6P) and similar inositol polyphosphates, such as 5-diphospho-inositol pentakisphosphate (5- InsP7); these are important intracellular signaling molecules (PubMed:27080106). {ECO:0000250|UniProtKB:Q9Z0U0, ECO:0000269|PubMed:23791524, ECO:0000269|PubMed:25938945, ECO:0000269|PubMed:27080106}. |EXS| |SPX| |cellular response to phosphate starvation|
