What is the official name of the SLC20A2 gene?
The official name of this gene is “solute carrier family 20 (phosphate transporter), member 2.”
SLC20A2 is the gene's official symbol. The SLC20A2 gene is also known by other names, listed below.

What is the normal function of the SLC20A2 gene?
The SLC20A2 gene provides instructions for making a protein called sodium-dependent phosphate transporter 2 (PiT-2). This protein plays a major role in regulating phosphate levels within the body (phosphate homeostasis) by transporting phosphate across cell membranes. Phosphate is needed for many functions including the breakdown of substances (metabolic processes), signaling between cells, and the production of DNA building blocks (nucleic acids) and fats. PiT-2 uses positively charged sodium atoms (ions) to transport phosphate across the cell membrane.
Does the SLC20A2 gene share characteristics with other genes?
The SLC20A2 gene belongs to a family of genes called SLC (solute carriers).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
