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 ATP-driven Ca(2+) ion pump involved in the maintenance of basal intracellular Ca(2+) levels at the presynaptic terminals (PubMed:18029012, PubMed:22912398, PubMed:25953895, PubMed:27035656). Uses ATP as an energy source to transport cytosolic Ca(2+) ions across the plasma membrane to the extracellular compartment (PubMed:25953895, PubMed:27035656). May counter-transport protons, but the mechanism and the stoichiometry of this Ca(2+)/H(+) exchange remains to be established (By similarity).CATALYTIC ACTIVITY Ca(2+)(in) + ATP + H2O = Ca(2+)(out) + ADP + phosphate + H(+)ACTIVITY REGULATION Down-regulated by YWHAE.SUBUNIT Interacts with PDZD11 (PubMed:12763866). Interacts (via N-terminus) with YWHAE (PubMed:18029012).SUBCELLULAR LOCATION Localized at parallel fiber terminals.ALTERNATIVE PRODUCTS There is a combination of two alternatively spliced domains at N-terminal site A (X and Z) and at C-terminal site C (A, B, E and G). The splice sites have mostly been studied independently. Full isoforms so far detected are isoform XA and isoform XB. Experimental confirmation may be lacking for some isoforms.TISSUE SPECIFICITY Highly expressed in the cerebellum (PubMed:8187550). Expressed in adrenal glands (PubMed:27035656).DEVELOPMENTAL STAGE Expressed in fetal skeletal muscle.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIB subfamily.
