Its catalytic domain is closely related to those of several other kinases, including mouse Mekk2, tobacco NPK, and yeast Ste11. Northern blot analysis revealed a 4. -kb transcript that appears to be ubiquitously expressed. Mitogen-activated protein kinase kinase kinase 3 directly regulates the stress-activated protein kinase (SAPK) and extracellular signal-regulated protein kinase (ERK) pathways by activating SEK and MEK1\/2 respectively; it does not regulate the p38 pathway. In cotransfection assays, it enhanced transcription from a nuclear factor kappa-B (NFKB)-dependent reporter gene, consistent with a role in the SAPK pathway. Alternatively spliced transcript variants encoding distinct isoforms have been observed.\u003c\/p\u003e\u003ch4\u003eReactivity\u003c\/h4\u003e\u003cp\u003eHuman;Mouse\u003c\/p\u003e\u003ch4\u003eClonality\u003c\/h4\u003e\u003cp\u003ePolyclonal\u003c\/p\u003e\u003ch4\u003eHost\u003c\/h4\u003e\u003cp\u003eRabbit\u003c\/p\u003e\u003ch4\u003eIsotype\u003c\/h4\u003e\u003cp\u003eIgG\u003c\/p\u003e\u003ch4\u003eImmunogen\u003c\/h4\u003e\u003cp\u003eThe antiserum was produced against synthesized peptide derived from human MAP3K3.
