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.

textDuring PINK1:PRKN-mediated mitophagy, the autophagy receptor optineurin (OPTN) forms a complex with the autophagy-related 9A (ATG9A) protein, a membrane-spanning protein that is recruited to the autophagosomal formation site (Yamamoto H et al., 2012; Yamano K et al., 2020). ATG9A localizes to the cytoplasmic single-membrane vesicles, termed ATG9 vesicles (Yamamoto H et al., 2012). OPTN recruits cytoplasmic ATG9A vesicles to damaged mitochondria (Yamano K et al., 2020), where these vesicles provide membrane contact sites delivering proteins and lipids during autophagosome formation (Yamamoto H et al., 2012; reviewed by Nishimura T & Tooze SA 2020). The leucine zipper domain of OPTN is required for the interaction with ATG9A (Yamano K et al., 2020). Disruptions of OPTN:ATG9A interaction inhibits mitophagy (Yamano K et al., 2020). Interactions between OPTN and other ATG proteins such as microtubule-associated proteins 1A/1B light chain 3B (MAP1LC3B or LC3) are implicated in autophagy.
