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 Serine/threonine kinase involved in various developmental processes (PubMed:10587646, PubMed:10962553, PubMed:11740943, PubMed:11872800, PubMed:12172554, PubMed:12893776, PubMed:14525946, PubMed:15466161, PubMed:15712201, PubMed:9601646). During early embryogenesis, acts as a survival protein (PubMed:10962553, PubMed:9601646). During mid-embryogenesis, phosphorylates and activates trh, a transcription factor required for tracheal cell fate determination (PubMed:11740943). Also regulates tracheal cell migration (PubMed:11740943, PubMed:14525946). Later in development, acts downstream of PI3K and Pk61C/PDK1 in the insulin receptor transduction pathway which regulates cell growth and organ size, by phosphorylating and antagonizing FOXO transcription factor (PubMed:10587646, PubMed:10962553, PubMed:11752451, PubMed:12893776, PubMed:24603715, PubMed:25329475, PubMed:29025897). Controls follicle cell size during oogenesis (PubMed:15712201). May also stimulate cell growth by phosphorylating Gig/Tsc2 and inactivating the Tsc complex (PubMed:12172554, PubMed:15466161). Dephosphorylation of 'Ser-586' by Phlpp triggers apoptosis and suppression of tumor growth (PubMed:10962553).CATALYTIC ACTIVITY L-seryl-[protein] + ATP = O-phospho-L-seryl-[protein] + ADP + H(+)CATALYTIC ACTIVITY L-threonyl-[protein] + ATP = O-phospho-L-threonyl-[protein] + ADP + H(+)SUBUNIT Interacts with trbl.INTERACTION Recruited to plasma membrane upon activation.ALTERNATIVE PRODUCTS Ubiquitously expressed. Present in ovary, where it is concentrated at the basal side of follicle cells.DEVELOPMENTAL STAGE Expressed both maternally and zygotically. Strongly expressed in embryo and pupa. Weakly expressed in larva. Mildly expressed in adult.DOMAIN Binding of the PH domain to the phosphatidylinositol 3-kinase alpha (PI(3)K) results in its targeting to the plasma membrane.PTM Phosphorylated and activated by Pk61C/PDK1 (PubMed:11344272). Phosphorylated on Ser-586 by the TORC2 complex (PubMed:10962553, PubMed:15718470, PubMed:22493059).DISRUPTION PHENOTYPE Death at the first instar larval stage (PubMed:9601646). Conditional RNAi-mediated knockdown in the female germline reduces ovary size (PubMed:24786828). RNAi-mediated knockdown in both larval salivary glands and fat body, results in small salivary glands displaying ectopic lipid storage and reduced expression of CdsA (PubMed:24603715).MISCELLANEOUS Major form.SIMILARITY Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. RAC subfamily.
