Validated All-in-One™ qPCR Primer for MAP3K4(NM_005922.3) Search again
Powered by BiozBy default, qPCR primer pairs are designed to measure the expression level of the splice variant (accession number) you selected for this gene WITHOUT consideration of other possible variants of this gene. If this gene has multiple variants, and you would like to measure the expression levels of one particular variant, multiple variants, or all variants, please contact us for a custom service project at inquiry@genecopoeia.com.

Each All-in-One™ qPCR Primer is experimentally validated to yield a single dissociation curve peak and to generate a single amplification of the correct size for the targeted gene. A cDNA Pool, containing reverse transcript products of 8 different human tissue total RNA(Liver, Testis,Muscle,Thyroid,Brain,Spleen,Stomach,Small Intestine)),was used as the qPCR validation template. qPCR was performed using 0.2 µM primer with 2XAll-in-One™ qPCR Mix (Catalog#: QP001,QP002,QP004,QP005). Reactions were incubated for 10min. at 95°C, followed by 40 cycles of 95°C for 10 sec.; 60°C, 20 sec. and 72°C, 15sec. using Bio-Rad iQ5™ Instrument. At the end of the last cycle, temperature was increased from 72 to 95°C to produce a melting curve. Panel A: Validated Result for Amplification Curve; Panel B: Validated Result for Melting Curve. |

Summary
The central core of each mitogen-activated protein kinase (MAPK) pathway is a conserved cascade of 3 protein kinases: an activated MAPK kinase kinase (MAPKKK) phosphorylates and activates a specific MAPK kinase (MAPKK), which then activates a specific MAPK. While the ERK MAPKs are activated by mitogenic stimulation, the CSBP2 and JNK MAPKs are activated by environmental stresses such as osmotic shock, UV irradiation, wound stress, and inflammatory factors. This gene encodes a MAPKKK, the MEKK4 protein, also called MTK1. This protein contains a protein kinase catalytic domain at the C terminus. The N-terminal nonkinase domain may contain a regulatory domain. Expression of MEKK4 in mammalian cells activated the CSBP2 and JNK MAPK pathways, but not the ERK pathway. In vitro kinase studies indicated that recombinant MEKK4 can specifically phosphorylate and activate PRKMK6 and SERK1, MAPKKs that activate CSBP2 and JNK, respectively but cannot phosphorylate PRKMK1, an MAPKK that activates ERKs. MEKK4 is a major mediator of environmental stresses that activate the CSBP2 MAPK pathway, and a minor mediator of the JNK pathway. Two alternatively spliced transcripts encoding distinct isoforms have been described. [provided by RefSeq].

- Axin utilizes distinct regions for competitive MEKK1 and MEKK4 binding and JNK activation.
- MEKK4 is the MAPK kinase kinase for TRAF4 regulation of the JNK pathway
- Taken together, these results indicate a novel role for CIN85 in the regulation of cellular stress response via the MAPK pathways.
- In this review, the role of MKK4 in cancer development appears complex, as some studies support a pro-oncogenic role for MKK4, while others suggest it may have tumor suppressor functions.
