| Background Information | Transcription factor MafK (UniProt Q61827; also known as Erythroid transcription factor NF-E2 p18 subunit, Nuclear factor erythroid derived 2 ubiquitous, p18 NF-E2) is encoded by the Mafk (also known as Nfe2u, AW061068) gene (Gene ID 17135) in murine species. MafK, MafG and MafF consistute a family of transcription factors that dimerize with the CNC (cap n collar) family regulatory protein Nrf2 (NF-E2 p45-related factor 2) via their bZip domain. The Nrf2/small Maf heterodimer regulates downstream genes, including those of phase II detoxifying enzymes, by targeting antioxidant responsive element (ARE) and Maf recognition element (MARE). |

| Key Applications |
|
| Application Notes | Western Blotting Analysis: A representative lot detected endogenous MafK as well as Zn+2-induced expression of exogenous MafK using nuclear extracts from a mouse erythroleukemia (MEL) cell line transfected with MafK cDNA in a metallothionein IIA gene promoter-driven expression plasmid (Igarashi, K., et al. (1995). Proc Natl Acad Sci U S A. 92(16):7445-7449). Chromatin Immunoprecipitation Analysis: A representative lot detected MafK association with the GST-P enhancer (GPE1) in rat hepatoma cells (H4IIE and dRLh84) and hyperplastic nodules/HN-bearing pre-neoplastic rat hepatocytes, but not in normal rat hepatocytes. While MafK association with the NAD(P)H:quinone oxidoreductase 1 (NQO1) antioxidant responsive element (ARE) was detected in all four sample types (Ikeda, H., et al. (2004). Biochem J. 380(Pt 2):515-521). Electrophoretic Mobility Shift Assay Analysis: A representative lot caused a supershift of MafK-containing complex in EMSA using radiolabeled oligonucleotides containing PBGD gene NF-E2 binding site and nuclear extracts from a mouse erythroleukemia (MEL) cell line induced to overexpress MafK (Igarashi, K., et al. (1995). Proc Natl Acad Sci U S A. 92(16):7445-7449). Electrophoretic Mobility Shift Assay (EMSA): A representative lot caused a supershift of both the constitutive and tBHQ-induced ARE-binding complex (Complex I and II, respectively) in EMSA using a radiolabeled oligonucleotide containing antioxidant responsive element (ARE) NF-E2 binding site and nuclear extracts from untreated and tBHQ-treated K562 cells (Kim, Y.C., et al. (2003). Oncogene. 22(12):1860-1865). |
