Biology:SLC26A2

Generic protein structure example

The SLC26A2 protein is a member of the solute carrier family. In humans, this transporter is encoded by the SLC26A2 gene.

Function

The diastrophic dysplasia sulfate transporter is a transmembrane glycoprotein implicated in the pathogenesis of several human chondrodysplasias. It apparently is critical in cartilage for sulfation of proteoglycans and extracellular matrix organization.

Clinical significance

Deficiencies are associated with many forms of osteochondrodysplasia. These include:

• achondrogenesis type 1B
• diastrophic dysplasia
• atelosteogenesis, type II
• recessive multiple epiphyseal dysplasia
