Protein: Sodium-dependent phosphate transport protein 2A (Sodium-phosphate transport protein 2A) (Na(+)-dependent phosphate cotransporter 2A) (NaPi-6) (Sodium/phosphate cotransporter 2A) (Na(+)/Pi cotransporter 2A) (NaPi-2a) (Solute carrier family 34 member 1) (Q28620)
Organism: Oryctolagus cuniculus (Rabbit)
Function: Involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane. The cotransport has a Na(+):Pi stoichiometry of 3:1 and is electrogenic (By similarity).
Subcellular location: Apical cell membrane {ECO:0000250|UniProtKB:Q06495}; Multi-pass membrane protein {ECO:0000255}. Cell membrane {ECO:0000250|UniProtKB:Q06496}; Multi-pass membrane protein {ECO:0000255}. Note=Localized at the brush border membranes of the proximal tubules. Internalized from the cell surface upon PTH stimulation. {ECO:0000250|UniProtKB:Q06496, ECO:0000250|UniProtKB:Q60825}.
