MAP3K3 (MEKK3) directly regulates MAPK8 and extracellular signal-regulated protein kinase (ERK) pathways by phosphorylating multiple MAP2Ks. Northern blot analysis revealed a 4. 6-kb transcript that appears to be ubiquitously expressed. This protein 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.
