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.

commentFUNCTION Heat shock protein that may play a role in the transport of polypeptides both across the mitochondrial membranes and into the endoplasmic reticulum.FUNCTION Acts as a highly immunodominant antigen (PubMed:15378761, PubMed:17051645, PubMed:8757872). Plays a role in the sensitivity to, and the import of candidacidal beta-defensin peptides (PubMed:16377704). HSP70/SSA1 and SSA2 bind histatin-5, a peptide from human saliva, and mediates its fungicidal activity (PubMed:12761219, PubMed:16720580, PubMed:17999963, PubMed:19006817, PubMed:9685398). SSA2 facilitates fungicidal activity of Hst 5 in binding and intracellular translocation, whereas HSP70/SSA1 appears to have a lesser functional role in Hst 5 toxicity (PubMed:16720580, PubMed:19006817).SUBUNIT Binds human histatin-5, an antifungal peptide from saliva.SUBCELLULAR LOCATION Expression is repressed by treatment with caspofungin.DOMAIN The regions defined by residues 128 to 135, 150 to 156 and 333 to 337 correspond to Hst 5-binding epitopes.DISRUPTION PHENOTYPE Does not affect cells growth and hyphal formation (PubMed:16720580). Leads to high resistance to the candidacidal activity of Hst 5 (PubMed:16377704, PubMed:16720580, PubMed:17999963).SIMILARITY Belongs to the heat shock protein 70 family.
