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 Non-selective voltage-gated ion channel that mediates the transport of anions and cations through the mitochondrion outer membrane and plasma membrane (PubMed:31935282). Forms a high-conducting channel with a stable open state and a voltage-induced closure with a mild preference for anions over cations (PubMed:31935282). Involved in male fertility and sperm mitochondrial sheath formation (By similarity).CATALYTIC ACTIVITY chloride(in) = chloride(out)CATALYTIC ACTIVITY K(+)(in) = K(+)(out)SUBUNIT Interacts with ARMC12 in a TBC1D21-dependent manner (By similarity). Interacts with MISFA (By similarity).SUBCELLULAR LOCATION May localize to non-mitochondrial membranes.ALTERNATIVE PRODUCTS Expressed in erythrocytes (at protein level) (PubMed:27641616). Widely expressed. Highest in testis (PubMed:9781040).DOMAIN Consists mainly of a membrane-spanning beta-barrel formed by 19 beta-strands.PTM Ubiquitinated by PRKN during mitophagy, leading to its degradation and enhancement of mitophagy. Deubiquitinated by USP30.SIMILARITY Belongs to the eukaryotic mitochondrial porin family.
