MEK5 Overexpression Lysate Summary

• Description:

  MEK5 Transient Overexpression Lysate

  
  Expression Host: HEK293T
  
  Plasmid: RC203171
  
  Accession#: NM_145160
  
  Protein Tag: C-MYC/DDK
  
  You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.
• Gene: MAP2K5

Applications/Dilutions

• Dilutions:
  • Western Blot
• Application Notes: This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.
  
  Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
• Theoretical MW: 49.9 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

• Storage: Store at -80C. Avoid freeze-thaw cycles.
• Buffer: RIPA buffer

Lysate Details for Array

• Type: Overexpression

Notes

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Background

Mitogen-acitvated protein kinase kinase 5 (MKK5) belongs to the serine/threonine protein kinase family and the MAPK kinase subfamily (MAP2K, MKK or MEKs). MAPKs require dual phosphorylation on threonine and tyrosine residues, an activation step carried out by MAPK kinase (1-2). The MAPK cascade plays an important role in signaling defense responses. Of the MKK family members, MKK5 exhibits the closest homology to MEK1 and MEK2, with 46% amino acid identity in the catalytic domain (3) MKK has been show to activate extracellular-signal-regulated protein kinase 5 (ERK5). Also, activated ERK5 phosphorylates mitogen- MKK5 extensively at Ser129, Ser137, Ser142 and Ser149, which are located within the region in MKK5 that is thought to interact with ERK5 (3). There have also been findings to that the MEK5 (MKK5)/ERK5 (BMK) pathway may play a role in prostate cancer (5).
