Summary: Enables MAP kinase kinase activity and protein serine/threonine kinase activity. Involved in MAPK cascade; cell surface receptor protein tyrosine kinase signaling pathway; and nervous system development. Acts upstream of with a positive effect on type B pancreatic cell proliferation. Acts upstream of or within several processes, including nervous system development; regulation of neuron projection development; and respiratory system development. Predicted to be located in several cellular components, including dendrite cytoplasm; perikaryon; and perinuclear region of cytoplasm. Predicted to be active in glutamatergic synapse and postsynaptic density. Is expressed in several structures, including alimentary system; blastocyst; brain; genitourinary system; and sensory organ. Used to study cardiofaciocutaneous syndrome. Human ortholog(s) of this gene implicated in carcinoma (multiple); cardiofaciocutaneous syndrome 3; high grade glioma; and melorheostosis. Orthologous to human MAP2K1 (mitogen-activated protein kinase kinase 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
