Protein

Sodium-dependent phosphate transporter 2

Gene

Slc20a2

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Sodium-phosphate symporter which seems to play a fundamental housekeeping role in phosphate transport by absorbing phosphate from interstitial fluid for normal cellular functions such as cellular metabolism, signal transduction, and nucleic acid and lipid synthesis. In vitro, sodium-dependent phosphate uptake is not siginificantly affected by acidic and alkaline conditions, however sodium-independent phosphate uptake occurs at acidic conditions. May play a role in extracellular matrix and cartilage calcification as well as in vascular calcification. Functions as a retroviral receptor (By similarity).By similarity
