The SLC26A1 and 2 genes encode proteins that facilitate sulfate (SO4(2-)) uptake into cells. The mechanism by which these transporters work is unclear but may be enhanced by extracellular halides or acidic pH environments, cotransporting one of several possible anions like hydrogen carbonate, oxalate, chloride or nitrate (reviewed in Mount & Romer, 2004; Alper & Sharma 2013). SLC26A1 encodes the sulfate anion transporter 1 (SAT1) (Bissig et al., 1994; Regeer et al., 2003) and is most abundantly expressed in the liver and kidney, with lower levels expressed in many other parts of the body. SLC26A2 is ubiquitously expressed and encodes a sulfate transporter (Diastrophic dysplasia protein, DTD, DTDST) (Hastbacka et al. 1994). This transporter provides sulfate for sulfation of glycosaminoglycan chains in proteoglycans needed for cartilage development. Defects in SLC26A2 are implicated in the pathogenesis of several human chondrodysplasias (reviewed in Rossi & Superti-Furga, 2001).
