Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Electrogenic Na(+)-coupled sugar symporter that actively transports D-glucose at the plasma membrane, with a Na(+) to sugar coupling ratio of 1:1 (PubMed:20980548, PubMed:28592437, PubMed:34880493, PubMed:37217492, PubMed:38057552). Transporter activity is driven by a transmembrane Na(+) electrochemical gradient set by the Na(+)/K(+) pump (PubMed:20980548, PubMed:28592437, PubMed:34880493). Unlike SLC5A1/SGLT1, requires the auxiliary protein PDZK1IP1/MAP17 for full transporter activity (PubMed:37217492). Has a primary role in D-glucose reabsorption from glomerular filtrate across the brush border of the early proximal tubules of the kidney (By similarity).CATALYTIC ACTIVITY D-glucose(out) + Na(+)(out) = D-glucose(in) + Na(+)(in)ACTIVITY REGULATION Enhanced by the interaction with PDZK1IP1/MAP17 (PubMed:37217492). Inhibited by natural product phlorizin and diabetic drugs, including empagliflozin and dapagliflozin, canagliflozin, and sotagliflozin (PubMed:20980548, PubMed:28592437, PubMed:38057552). Empagliflozin is selective for SLC5A2/SGLT2 over SLC5A1/SGLT1 and it inhibits by occupying the sugar-binding site in SLC5A2 (PubMed:34880493).SUBUNIT Forms a heterodimer (via TM13) with PDZK1IP1 (via N-terminal transmembrane helix); this interaction enhances SLC5A2 transporter activity.INTERACTION The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the sodium:solute symporter (SSF) (TC 2.A.21) family.
