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.

| text | The precise order of events leading to the circularization of poly (A) mRNA during translation initiation is unknown. Here the association of PABP with the poly (A) mRNA and the association of PABP with eIF4F are represented as occuring simultaneously after formation of the initiation complex. However, it is also possible that these interactions occur during the formation of the translation initiation complex. The binding of eIF4F to the cap and binding of PABP to the poly (A) tail, for example, may occur at the same time. In fact, the eIF4G-PABP interaction helps eIF4F to bind tighter to the cap (Borman et al. 2000.) In addition, eIF4B and eIF4H bind more transiently to the mRNA and may not be part of an initial complex in which PABP has not yet touched eIF4G. |
