MOS is a serine/threonine kinase that activates the MAP kinase cascade through direct phosphorylation of the MAP kinase activator MEK (MAP2K1; MIM 176872).MOS (MOS Proto-Oncogene, Serine/Threonine Kinase) is a Protein Coding gene. Diseases associated with MOS include Sarcoma. Among its related pathways are Oocyte meiosis and MAPK signaling pathway. GO annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is MAP3K21.MOS (MOS Proto-Oncogene, Serine/Threonine Kinase) is a Protein Coding gene. Diseases associated with MOS include Sarcoma.
