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.

textThe N‑terminal fragment of gasdermin E (GSDME(1-270)) produced by cleavage by caspase-3 (CASP3) or granzyme B (GZMB) targets the plasma membrane (Rogers C et al. 2017; Wang Y et al. 2017). In vitro oligomerization assays showed that GSDME(1-270) formed dimers and high‑molecular weight oligomers when incubated with purified cell membranes from human embryonic kidney 293 (HEK293T) cells (Rogers C et al. 2019). Structural and biochemical studies suggest that the N‑terminal fragments of gasdermins form membrane‑spanning pores allowing release of inflammatory molecules such as interleukin (IL)‑1β, IL‑18, and high‑mobility group box 1 (HMGB1) and eventually causing cell rupture (Shi J et al. 2015; Ding J et al. 2016; Liu X et al. 2016; Feng S et al. 2018; Mulvihill E et al. 2018). Phosphorylation of GSDME at T6 may influence its pore‑forming activity (Rogers C et al. 2019).
