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 Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit (By similarity). May mediate the control of various cellular processes by insulin-like peptides. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains. Involved in control of cell proliferation, cell size, and body and organ growth throughout development. Also has a role in a signaling pathway controlling the physiological response required to endure periods of low nutrient conditions. Insulin/insulin-like growth factor (IGF) signaling pathway has a role in regulating aging and is necessary in the ovary for vitellogenic maturation.SUBUNIT Bindings to phosphatidylinositol 3-kinase and SHP2.DEVELOPMENTAL STAGE Expressed during G1, S and G2 phase of the cell cycle.DISRUPTION PHENOTYPE Female sterile. Extends fruit fly median life-span by up to 48% in homozygotes and 36% in heterozygotes.MISCELLANEOUS 'Chico' means 'small boy' in Spanish.SEQUENCE CAUTION Truncated N-terminus.
