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 | Catalyzed by the RNA polymerase activity of the viral PB1 subunit, an mRNA complementary to the bound vRNA is synthesized (Plotch, 1977). PA and PB2 move down the growing mRNA in complex with PB1, with PB2 possibly dissociating from the cap (Braam, 1983). However, the 5’ end of the vRNA may remain bound during elongation as the template is threaded through in a 3’ to 5’ direction until a polyadenylation signal is encountered (Poon, 1998; Zheng, 1999). A poly-uridine sequence motif, consisting in most cases of 5-7 U residues, abuts the "panhandle" duplex structure in the vRNA; this sequence is approximately 16 nucleotides from the 5' end of this RNA duplex structure within the vRNA promoter. Encountering this signal, the viral RNA polymerase stutters, leading to the synthesis of a poly-A tail on the viral mRNA (Robertson, 1981; Luo, 1991; Li,1994; Poon, 1998; Zheng et al. 1999). |
