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.

textActivin binds the Activin receptor composed of a type II receptor (ACVR2A/B) and a type I receptor, in this case ACVR1B (ALK4) (Attisano et al. 1996, Zhou et al. 2000). Activin appears to interact initially with the type II receptor component (Attisano et al. 1996). It is unclear if the type II and type I receptors are associated before binding Activin. Any of Activin A (INHBA:INHBA), Activin AB (INHBA:INHBB), and Activin B (INHBB:INHBB) can bind and signal via an activin receptor containing the ACVR1B (ALK4) type I receptor. Also, TGFBR3 (Betaglycan) antagonises Activin signalling by binding with Inhibin A and ACVR2A (ActRII). TGFBR3 and Activin compete for ACVR2A and TGFBR3 thus inhibits activin signalling (Lewis et al. 2000, Waiter et al. 2003).
