Antigen/Purification: ExpandCollapse

The antigen is a peptide from the C-terminal region, specific to the human Mnk2a isoform.  The sequence of the antigen has no homology with Mnk1 or Mnk2b.

The antibody is prepared from pooled rabbit serum by affinity purification using a column to which the peptide immunogen was coupled.

Biological Significance: ExpandCollapse

MAP kinase-interacting kinases Mnk1 and Mnk2 are activated by the MAP kinases, ERK and p38 (Waskiewicz et al., 1997).  Additionally, Mnk1 and Mnk2 have been shown to phosphorylate the translation initiation factor eIF4E (Fukunaga and Hunter 1997; Waskiewicz et al., 1997).   Alternative splicing of the MKNK2 gene results in two isoforms with different C-termini: one that has a MAPK-binding domain, Mnk2a, and one that does not, Mnk2b (Parra et al., 2005).  Recent studies have indicated that Mnk2a has tumor suppressive activity while Mnk2b is pro-oncogenic (Maimon et al., 2014).

Storage

100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Western blot of HeLa lysate showing specific immunolabeling of the ~52 kDa Mnk2a isoform in the third lane (-). Specificity is shown in the second lane (Mnk2a) where immunolabeling is blocked by preadsorption of the Mnk2a peptide used as the antigen, but not by the Mnk2b peptide in the first lane.
