产品介绍
Pokemon(7APOK Erythroid Myeloid Ontogenic factor)能够控制将正常细胞变成癌细胞所需的途径,Pokemon蛋白是转录因子蛋白家族的一员,并且在人类癌症中发生了突变。另外Pokemon蛋白作为转录因子参与一些细胞基因转录的调节,并在细胞分化过程中发挥着关键、多效性的功能。近来发现,Poke-mon在致癌转化过程中发挥着至关重要的功能,并与肿瘤的发生密切相关。 这种蛋白很可能在实质肿瘤中处于重要地位,还有学者认为:Pokemon在一定类型的B细胞和T细胞淋巴瘤中水平非常高,并发现具有高水平Pokemon蛋白表达对肿瘤恶性程度改变更大。
Pokemon, the POK erythroid myeloid ontogenic factor, not only regulates the expression of many genes, but also plays an important role in cell tumorigenesis. To investigate the molecular mechanism regulating expression of the Pokemon gene in humans, its 5'-upstream region was cloned and analyzed. Transient analysis revealed that the Pokemon promoter is constitutive. Deletion analysis and a DNA decoy assay indicated that the NEG-U and NEG-D elements were involved in negative regulation of the Pokemon promoter, whereas the POS-D element was mainly responsible for its strong activity. Electrophoretic mobility shift assays suggested that the NEG-U, NEG-D and POS-D elements were specifically bound by the nuclear extract from A549 cells in vitro. Mutation analysis demonstrated that cooperation of the NEG-U and NEG-D elements led to negative regulation of the Pokemon promoter. Moreover, the NEG-U and NEG-D elements needed to be an appropriate distance apart in the Pokemon promoter in order to cooperate. Taken together, our results elucidate the mechanism underlying the regulation of Pokemon gene transcription, and also define a novel regulatory sequence that may be used to decrease expression of the Pokemon gene in cancer gene therapy. mol wt:kDa Other Aliases: Factor binding IST protein 1; Factor that binds to inducer of short transcripts protein 1; FBI-1; FBI1; HIV-1 1st-binding protein 1; Leukemia/lymphoma related factor; LRF; Pokemon; TIP21; TTF-I interacting peptide 21; ZBTB7; ZBTB7A; Zinc finger and BTB domain-containing protein 7A
