Proteins/UNIPROT:Q9UBH6
Inorganic ion transporter that mediates phosphate ion export across the plasma membrane. Plays a major role in phosphate homeostasis, preventing intracellular phosphate accumulation and possible calcium phosphate precipitation, ultimately preserving calcium signaling. Binds inositol hexakisphosphate (Ins6P) and similar inositol polyphosphates, such as 5-diphospho-inositol pentakisphosphate (5-InsP7), which are important intracellular signaling molecules involved in regulation of phosphate flux..
