Summary: Enables phosphate transmembrane transporter activity. Involved in several processes, including plasma membrane selenite transport; polyphosphate metabolic process; and regulation of phosphate transmembrane transport. Located in plasma membrane. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 25. Orthologous to several human genes including SLC13A4 (solute carrier family 13 member 4).

What's a GeneRIF?

Pho87 and Pho90 represent non-redundant P(i) transporters, which are tuned by the integration of multiple nutrient signalling mechanisms in order to adjust P(i)-transport capacity to the general nutritional status of the environment.
Title: Differential roles for the low-affinity phosphate transporters Pho87 and Pho90 in Saccharomyces cerevisiae.
However, our results revealed that Ddi1p and its associated protein Rad23p are not involved in the decrease in Pho81p level under high-phosphate condition.
Title: Ddi1p and Rad23p play a cooperative role as negative regulators in the PHO pathway in Saccharomyces cerevisiae.

Preferred Names: SPX domain-containing inorganic phosphate transporter

NP_009966.2

Low-affinity inorganic phosphate (Pi) transporter; acts upstream of Pho81p in regulation of PHO pathway; targeted to vacuole via AP-3 pathway; expression is independent of Pi concentration and Pho4p activity; contains 12 membrane-spanning segments; PHO87 has a paralog, PHO90, that arose from the whole genome duplication
