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.

textRecruitment of the C8 trimeric complex is mediated by the C8 beta chain (Monahan & Sodetz 1981). Binding enables C8 to undergo necessary conformational rearrangements that allow the C8 alpha chain to penetrate into the hydrophobic core of the lipid bilayer (Stecket et al. 1983, Weiland et al. 2014), firmly anchoring the C5b:C6:C7:C8 complex to the target cell membrane. A functional membrane pore can be formed by the C5b:C6:C7:C8 complex (Boyle et al. 1976, Tegla et al. 2011). These pores are small and unstable but can cause cell lysis if present in sufficient number (Martin et al. 1987). They also increase cytosolic free Ca2+ concentration and thereby stimulate signalling pathways (Koski et al. 1983, Niculescu & Rus 2001).
