Summary: Enables MAP kinase kinase activity and kinase binding activity. Involved in several processes, including intracellular signal transduction; regionalization; and transmembrane receptor protein tyrosine kinase signaling pathway. Located in condensed chromosome. Colocalizes with nuclear envelope. Is expressed in adult head and organism. Used to study cancer. Human ortholog(s) of this gene implicated in carcinoma (multiple); cardiofaciocutaneous syndrome 3; cardiofaciocutaneous syndrome 4; high grade glioma; and melorheostosis. Orthologous to human MAP2K1 (mitogen-activated protein kinase kinase 1) and MAP2K2 (mitogen-activated protein kinase kinase 2). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Ras-Dsor1 activity is independent of upstream activation by EGFR, and instead it appears to be activated by the insulin-like growth factor receptor to promote Wg signaling.
Title: Ras-activated Dsor1 promotes Wnt signaling in Drosophila development.
the Ras/MEK/MAPK pathway regulates regional-fate specification via HSPGs during development
Title: Ras/MEK/MAPK-mediated regulation of heparin sulphate proteoglycans promotes retinal fate in the Drosophila eye-antennal disc.
RNAi-mediated inhibition of MAPK-signaling by knockdown of Ras85D, phl/D-Raf or Dsor1/MEK affects larval development, adult life span and hemolymph phosphate, suggesting that some in vivo effects involve activation of this signaling pathway by phosphate.
Title: Genetic determinants of phosphate response in Drosophila.
Gem and Brm act antagonistically to modulate the EGFR-Ras-MAPK signaling pathway, by affecting Mek levels during Drosophila development
