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 Plasma membrane Na(+)/H(+) antiporter. Mediates the electroneutral exchange of intracellular H(+) ions for extracellular Na(+) (PubMed:10444453). Major apical Na(+)/H(+) exchanger in the base of the colonic crypt. Controls in the colonic crypt intracellular pH (pHi) to direct colonic epithelial cell differentiation into the absorptive enterocyte lineage at the expense of the secretory lineage (By similarity).CATALYTIC ACTIVITY Na(+)(in) + H(+)(out) = Na(+)(out) + H(+)(in)SUBUNIT Interacts with CHP1 and CHP2.SUBCELLULAR LOCATION Expressed in skeletal muscle, colon and kidney. Lower levels in the testis, prostate, ovary, and small intestine (PubMed:10444453, PubMed:8843774). In the distal colon, expressed along the cryptal axis (PubMed:8843774).SIMILARITY Belongs to the monovalent cation:proton antiporter 1 (CPA1) transporter (TC 2.A.36) family.CAUTION The number, localization and denomination of hydrophobic domains in the Na(+)/H(+) exchangers vary among authors.
