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 Component of a P4-ATPase flippase complex which catalyzes the hydrolysis of ATP coupled to the transport of aminophospholipids from the outer to the inner leaflet of various membranes and ensures the maintenance of asymmetric distribution of phospholipids. Phospholipid translocation also seems to be implicated in vesicle formation and in uptake of lipid signaling molecules (Probable).CATALYTIC ACTIVITY ATP + H2O + phospholipidSide 1 = ADP + phosphate + phospholipidSide 2.COFACTOR Component of a P4-ATPase flippase complex which consists of a catalytic alpha subunit and an accessory beta subunit (Probable). Interacts with beta subunits TMEM30A and TMEM30B.INTERACTION Ubiquitously expressed at moderate levels.SIMILARITY Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IV subfamily.SEQUENCE CAUTION Contaminating sequence. Sequence of unknown origin inserted in the coding sequence.
