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 Interconverts simultaneously and stereospecifically pyruvate and lactate with concomitant interconversion of NADH and NAD(+).CATALYTIC ACTIVITY (S)-lactate + NAD(+) = pyruvate + NADH + H(+)PATHWAY Fermentation; pyruvate fermentation to lactate; (S)-lactate from pyruvate: step 1/1.SUBUNIT Homotetramer (PubMed:11276087). Interacts with PTEN upstream reading frame protein MP31; the interaction leads to inhibition of mitochondrial lactate dehydrogenase activity, preventing conversion of lactate to pyruvate in mitochondria (PubMed:33406399).INTERACTION Predominantly expressed in aerobic tissues such as cardiac muscle.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the LDH/MDH superfamily. LDH family.ONLINE INFORMATION Lactate dehydrogenase entryONLINE INFORMATION Another dark horse - Issue 109 of September 2009
