General Information
Term MAPK cascade ID (Ontology) GO:0000165 (Gene Ontology)
Definition An intracellular protein kinase cascade containing at least a MAP kinase (MAPK). It starts with the activation of a MAP3K, and the consecutive activation of a MPK2K and a MAPK. The cascade can also contain an additional tier: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.[ PubMed:20811974 PubMed:9561267 ]
Also Known As "MAP kinase cascade" ; "MAP kinase kinase kinase cascade" ; "MAPK signal transduction" (for all, see Synonyms field below)
