Scientific Background

Mitogen-activated protein kinase (MAPK) signaling cascades include MAPK or extracellular signal-regulated kinase (ERK), MAPK kinase (MKK or MEK), and MAPK kinase kinase (MAPKKK or MEKK). MAPKK kinase/MEKK phosphorylates and activates its downstream protein kinase, MAPK kinase/MEK, which in turn activates MAPK. The kinases of these signaling cascades are highly conserved, and homologs exist in yeast, Drosophila, and mammalian cells. MAPKKK5 contains 1,374 amino acids with all 11 kinase subdomains. Northern blot analysis shows that MAPKKK5 transcript is abundantly expressed in human heart and pancreas. The MAPKKK5 protein phosphorylates and activates MKK4 (aliases SERK1, MAPKK4) in vitro, and activates c-Jun N-terminal kinase (JNK)/stress-activated protein kinase (SAPK) during transient expression in COS and 293 cells; MAPKKK5 does not activate MAPK/ERK.

What species does this antibody react with?
This antibody has been validated for reactivity against Human, Mouse, Rat. Actual cross-reactivity is determined by immunogen sequence homology across species. Contact technical support for unlisted species.
What applications has this antibody been validated for?
Validated applications include: Western Blot (WB), Immunohistochemistry (IHC), ELISA. Each application was tested with positive and negative controls. Contact our team regarding applications not listed.
How was this antibody produced and purified?
This polyclonal IgG antibody was raised in rabbit against a synthesized target-specific peptide. It was affinity-purified from antiserum using an epitope-specific immunogen, yielding a highly specific antibody suitable for multiple research applications.
What is the expected molecular weight of MAP3K5?
The predicted molecular weight of MAP3K5 is ~154.5 kDa. Band size may vary slightly depending on post-translational modifications and gel percentage.
What storage conditions does this antibody require?
Store at −20°C for long-term storage. Avoid repeated freeze-thaw cycles. Working aliquots can be stored at 4°C for short-term use. The formulation includes 50% glycerol as a cryoprotectant.
Is this antibody specific for the phosphorylated form of MAP3K5?
Yes. This antibody is designed to detect MAP3K5 only at the phosphorylation site specified in the product name. Lambda phosphatase treatment eliminates the signal, confirming phospho-specificity.
