ID:M3K1_HUMAN DESCRIPTION: RecName: Full=Mitogen-activated protein kinase kinase kinase 1; EC=2.7.11.25; AltName: Full=MAPK/ERK kinase kinase 1; Short=MEK kinase 1; Short=MEKK 1; FUNCTION: Component of a protein kinase signal transduction cascade. Activates the ERK and JNK kinase pathways by phosphorylation of MAP2K1 and MAP2K4. Activates CHUK and IKBKB, the central protein kinases of the NF-kappa-B pathway. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. COFACTOR: Magnesium. ENZYME REGULATION: Activated by autophosphorylation on Thr-1400 and Thr-1412 following oligomerization. SUBUNIT: Binds both upstream activators and downstream substrates in multimolecular complexes through its N-terminus. Oligomerizes after binding MAP4K2 or TRAF2. Interacts with AXIN1. Interacts (via the kinase catalytic domain) with STK38. INTERACTION: P45985:MAP2K4; NbExp=3; IntAct=EBI-49776, EBI-447868; Q12851:MAP4K2; NbExp=2; IntAct=EBI-49776, EBI-49783; PTM: Autophosphorylated (By similarity). DISEASE: Defects in MAP3K1 are the cause of 46,XY sex reversal type 6 (SRXY6) [MIM:613762]. SRXY6 is a disorder of sex development. Affected individuals have a 46,XY karyotype but present as phenotypically normal females. SIMILARITY: Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily. SIMILARITY: Contains 1 protein kinase domain. SIMILARITY: Contains 1 RING-type zinc finger. SIMILARITY: Contains 1 SWIM-type zinc finger.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
