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 Subunit k, of the mitochondrial membrane ATP synthase complex (F(1)F(0) ATP synthase or Complex V) that produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain (Probable). ATP synthase complex consist of a soluble F(1) head domain - the catalytic core - and a membrane F(1) domain - the membrane proton channel (By similarity). These two domains are linked by a central stalk rotating inside the F(1) region and a stationary peripheral stalk (By similarity). During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation (Probable). In vivo, can only synthesize ATP although its ATP hydrolase activity can be activated artificially in vitro (By similarity). Part of the complex F(0) domain (By similarity). Required for dimerization of the ATP synthase complex and as such regulates ATP synthesis in the mitochondria (PubMed:21345788, PubMed:29917077).SUBUNIT Component of the ATP synthase complex composed at least of ATP5F1A/subunit alpha, ATP5F1B/subunit beta, ATP5MC1/subunit c (homooctamer), MT-ATP6/subunit a, MT-ATP8/subunit 8, ATP5ME/subunit e, ATP5MF/subunit f, ATP5MG/subunit g, ATP5MK/subunit k, ATP5MJ/subunit j, ATP5F1C/subunit gamma, ATP5F1D/subunit delta, ATP5F1E/subunit epsilon, ATP5PF/subunit F6, ATP5PB/subunit b, ATP5PD/subunit d, ATP5PO/subunit OSCP (By similarity). ATP synthase complex consists of a soluble F(1) head domain (subunits alpha(3) and beta(3)) - the catalytic core - and a membrane F(0) domain - the membrane proton channel (subunits c, a, 8, e, f, g, k and j) (By similarity). These two domains are linked by a central stalk (subunits gamma, delta, and epsilon) rotating inside the F1 region and a stationary peripheral stalk (subunits F6, b, d, and OSCP) (By similarity). The ATP synthase complex/complex V exists as a monomeric and a dimeric supercomplex that helps shape mitochondrial cristae to optimize proton flow (PubMed:29917077).SUBCELLULAR LOCATION Transactivated by SBP1.DISEASE The disease is caused by variants affecting the gene represented in this entry.
