Abstract / Description of output

The mouse heat shock factor 2 (HSF2) cDNA was previously cloned by homology to HSF1, the heat shock factor involved in the cellular response to stress [Sarge, K.D., Zimarino, V., Holm, K., Wu, C., Morimoto, R.I., Cloning and characterization of two mouse heat shock factors with distinct inducible and constitutive DNA-binding ability. Genes Dev. 5 (1991) 1902-1911]. HSF2 is active in restricted cell types during pre- and post-implantation stages of development, and only in male germ cells of adult mice. However, the function of this factor remains elusive. We report here the cloning of the mouse Hsf2 gene and its genomic structure. We show that the gene is composed of 13 exons of variable sizes spanning at least 43kb in the genome. The transcription start site has been determined, and upstream sequences with promoter activity have been identified by their ability to direct the expression of a luciferase reporter gene in transfected cells. A preliminary analysis of the proximal promoter sequence determined that the TATA box is absent, but that a GC-rich region with several potential binding sites for transcription factors is present. The gene has been mapped to mouse chromosome 10 by in-situ hybridization on metaphase chromosomes.
