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.

literatureReference[LiteratureReference:4793701] Redox regulation of mammalian heat shock factor 1 is essential for Hsp gene activation and protection from stress
[LiteratureReference:4793704] Activation of heat shock gene transcription by heat shock factor 1 involves oligomerization, acquisition of DNA-binding activity, and nuclear localization and can occur in the absence of stress
textDuring the mitochondrial unfolded protein response (mtUPR), HSF1 is activated by phosphorylation (Katiyar et al. 2020, also observed during heat shock in Sarge et al. 1993), translocation from the cytosol to the nucleus (Baler et al. 1993, Sarge et al. 1993, Sutandy et al. 2023, Katiyar et al. 2020), trimerization (Baler et al. 1993 and inferred from the mouse homolog in Sarge et al. 1993, Katiyar et al. 2020), and possible oxidation of two cysteine residues (Cys-35 and Cys-105, inferred from the mouse homolog in Anh and Thiele 2003) in an uncharacterized order of events. These alterations expose the DNA-binding domain of HSF1, causing HSF1 to bind DNA elements of target genes (Baler et al. 1993).
