• Conditional description: Stable transfectant, conditional functionality: MEKK3 kinase activity and ERK1/2, JNK and p38 signalling pathways activated following 4-hydroxytamoxifen (4-HT) treatment of cells.
• Description: HM3 cells are HEK 293 cells stably expressing conditional kinase ∆MEKK3:ER* from the pBabePuro plasmid. ∆MEKK3:ER* consists of the isolated kinase domain of MEKK3 fused in-frame to a modified form of the hormone binding domain of the estrogen receptor (hbER*) that can be de-repressed by 4-hydroxytamoxifen (4-HT) but not β-estradiol. In this case the * refers to a point mutation that ablates estradiol binding but allows 4-HT binding. Activation of ∆MEKK3:ER* leads to the strong activation of the JNK and p38 pathways and a weaker activation of ERK1/2. This cell line can be used to study the role and factors impacting on the JNK, p38 and ERK1/2 signalling pathways such as gene expression, cell proliferation, cell cycle arrest and cell death.. The cells are puromycin resistant. Conditional kinase activation of ∆MEKK3:ER* can be induced with 100nM 4-HT.
• Production details: HEK 293 cells were transfected with the pBabePuro plasmid expressing â?‚ˆ?‚†MEKK3:ER*. Stable transfectants were selected using puromycin and ring cloning.
