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 | Cell stimulation by Interleukin-12 (IL12) leads to formation of Signal transducer and activator of transcription 4 (STAT4) dimers but not heterodimers with STAT1 or STAT3 (Naeger et al. 1999). STAT4 is required to mediate IL12 effects and is crucial for T cell helper 1 (Th1) development and efficient Interferon gamma (IFNG) production, as shown by STAT4 knock-out studies (Kaplan et al. 1996, Thierfelder et al. 1996). STAT4 is activated by the interaction of IL12 with the interleukin-12 receptor. The interaction of the STAT4 SH2 domain is specific for the peptide sequence pYLPSNID, which contains tyrosine 800 in the Interleukin-12 receptor beta 2 subunit (IL12RB2). This tyrosine is required for STAT4 DNA binding activity and transcriptional activation of the Interferon regulatory factor 1(IRF1) gene. STAT4 is not capable of binding other peptide sequences at tyrosine residues 678 or 767 of IL12RB2 and these peptides are not required for STAT4 activation. The Interleukin-12 receptor peptide sequence pYLPSNID appears to be a specific binding site for STAT4, other STATs, including STAT1, which has a closely related SH2 domain, do not recognize pYLPSNID peptides (Naeger et al. 1999). |
