| abstractText | The insulin receptor gene is induced 8 to 10-fold during adipocyte differentiation. Plasmids containing the promoter, exon 1 and a portion of the first intron from either the mouse or human gene are able to modulate the expression of an insulin receptor/CAT gene 3 to 7-fold during differentiation. We have shown that several nuclear proteins from both preadipocyte and adipocyte nuclear extracts bind to two discrete sites within a 278-bp region in the 5' end of the first intron. Sequence comparison between the first intron of the human gene and the mouse gene shows two regions of sequence identity which correspond to the protein binding regions detected by Dnase footprinting. One of these sites binds proteins that are enriched in adipocyte nuclear extracts and can be competed by adipose regulatory element, ARE6. |
