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 Involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane (PubMed:12324554, PubMed:20335586, PubMed:26047794, PubMed:8327470). The cotransport has a Na(+):Pi stoichiometry of 3:1 and is electrogenic (By similarity).CATALYTIC ACTIVITY 3 Na(+)(out) + phosphate(out) = 3 Na(+)(in) + phosphate(in)BIOPHYSICOCHEMICAL PROPERTIES Optimum pH is 8.0.SUBUNIT Interacts via its C-terminal region with NHERF4 (By similarity). Interacts with NHERF1 (PubMed:22506049). Interacts with TMEM174; regulates SLC34A1 internalization by PTH and FGF23 (By similarity).INTERACTION Localized at the brush border membranes of the proximal tubules. Internalized from the cell surface upon PTH stimulation.ALTERNATIVE PRODUCTS Kidney and lung.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the SLC34A transporter family.
