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 Constitutively active serine/threonine-protein kinase that exhibits growth-factor-independent kinase activity and that may participate in p53/TP53-dependent cell growth arrest signaling and play an inhibitory role during embryogenesis.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(+)COFACTOR Constitutively activated by phosphorylation at Ser-232, Ser-372, and Ser-389 in serum-starved cells. Does not require growth factor stimulation for significant kinase activity.SUBUNIT Forms a complex with MAPK3/ERK1 but not with MAPK9 or MAPK14 in serum-starved cells.INTERACTION Predominantly cytosolic.ALTERNATIVE PRODUCTS Phosphorylated at Ser-232, Ser-372, and Ser-389 in serum-starved cells.SIMILARITY Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily.
