Sugar transporter SWEET1

(Redirected from SLC50A1)

Sugar transporter SWEET1, also known as RAG1-activating protein 1 and stromal cell protein (SCP), is a membrane protein that in humans is encoded by the SLC50A1 gene.[5] SWEET1 is the sole transporter from the SLC50 (SWEET) gene family present in the genomes of most animal species, with the exception of the nematode Caenorhabditis elegans, which has seven.[6]

SWEET1 is a broadly-expressed glucose transporter.[6] As the SWEET family has been identified relatively recently, the full range of its functions in animals is not yet clear.[7] However, the bovine SLC50A1 homologue is associated with lactose concentration in milk,[8] and the CiRGA homologue in the sea squirt Ciona intestinalis is essential for tissue differentiation during embryogenesis, especially the development of the notochord.[9] SWEET genes are common in plant genomes, with around twenty paralogues [6] functioning as both sucrose and hexose transporters, and are also associated with pathogen susceptibility.[6][10]
