The antibody detects endogenous levels of Pim-1 only when phosphorylated at tyrosine 309.
Purification
Antibodies were purified by affinity-chromatography using epitope-specific peptide.
Immunogen
Pim-1 (phospho Tyr309) antibody was raised against a peptide sequence around phosphorylation site of tyrosine 309 (A-A-V (p)-W-S) derived from Human Pim-1.
Proto-oncogene with serine/threonine kinase activity involved in cell survival and cell proliferation and thus providing a selective advantage in tumorigenesis. Exerts its oncogenic activity through: the regulation of MYC transcriptional activity, the regulation of cell cycle progression and by phosphorylation and inhibition of proapoptotic proteins (BAD, MAP3K5, FOXO3). Phosphorylation of MYC leads to an increase of MYC protein stability and thereby an increase of transcriptional activity. The stabilization of MYC exerted by PIM1 might explain partly the strong synergism between these two oncogenes in tumorigenesis.
