Sodium-dependent phosphate transporter

Sodium-dependent phosphate transporter refers to a type of membrane protein that facilitates the transport of phosphate ions across cell membranes. This transporter is dependent on the sodium gradient, which is maintained by the sodium-potassium pump, to drive the movement of phosphate against its concentration gradient. This process is essential for maintaining phosphate homeostasis in cells and organisms. It is mainly divided into PIT-1, PIT-2 and PIT-3 subtypes, which have different tissue distribution and functions.
