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.

textSide branching is the most popular and well accepted model for actin polymerization. According to this hypothesis activated ARP2/3 complex binds to the side of a pre?existing (mother) actin filament and induces the formation of end?side junctions between filaments by linking the pointed end of a newly nucleated filament to the side of a pre?existing one (Thomas et al. 2004, Mullins et al. 1998). Branching occur preferentially near the barbed end of the mother filament. The ARP2/3 complex acts as a pointed end capper for the nascent daughter filament and the two ARPs forms the first two subunits in this daughter filament. ATP hydrolysis on G?actin after incorporation at the branch destabilises its interaction with membrane?bound activator, leading to detachment of the branched junction (Le Clainche & Carlier 2008, Le Clainche et al. 2003).
