We have isolated a genomic clone containing the mouse neu gene. The 5' end of the mouse neu gene was localized by Southern analysis, subcloned and characterized. DNA sequence analysis revealed that the promoter region is 67% G+C-rich and lacks a TATA box, although a CAAT box is present. By sequence comparison, we identified several consensus recognition sequences for general transcription factors such as Sp1, E4TF1, AP2, OTF-1 and GCF, as well as recognition sequences for RVF, E1A and GTG, which have recently been identified in the rat neu promoter. Functional promoter activity was demonstrated by the ability of the promoter to drive transcription of the bacterial chloramphenicol acetyltransferase gene. Using a series of 5'-end deletion mutants, we have identified multiple positive and negative cis-acting elements that regulate mouse neu gene transcription.

Seventeen kilobases of genomic DNA containing the promoter and the coding region of the round-spotted pufferfish JAK1 gene was isolated and completely sequenced. This gene consists of 25 exons and 24 introns spanning about 13.5 kb, compared to > 30kb in carp JAK1 gene. Primer extension analysis revealed one transcription initiation site which was 376 bp upstream of the translation initiation site. The sequence of the 2.9 kb region upstream of the transcription initiation site contains numerous potential binding sites for transcription factors including HNF-5, GCF, Sp1, CRE, AP2, GATA, GAGA, E2A, p53, and NF-IL6. When this region was placed upstream of the chloramphenicol acetyltransferase (CAT) reporter gene and transfected into a carp CF cell line, it could drive the synthesis of CAT enzyme three times more efficiently than could the common carp JAK1 promoter.
