Isolation and nucleotide sequence of a mouse histidine tRNA gene.

We have sequenced a 1307 base pair mouse genomic DNA fragment which contains a histidine tRNA gene. The sequence of the putative mouse histidine tRNA differs from the published sequence of sheep liver histidine tRNA by a single base change in the D-loop. It does not contain an unpaired 5' terminal G residue, as reported for Drosophila and sheep histidine tRNAs. The gene does not contain introns. The 3' flanking region contains a typical RNA polymerase III termination site of 6 consecutive T residues. 523 residues after the 3' end of the his tRNA coding region, the mouse DNA contains a sequence 72% homologous to part of the consensus sequence of the B1 (alu) family.     

Identification of mouse adenovirus type 1 early region 1: DNA sequence and a conserved transactivating function.

The left end of the genome of mouse adenovirus type 1 (also known as strain FL) was characterized by determination of the DNA sequence, amino acid similarities with early region proteins of primate adenoviruses, and a functional assay. Several specific DNA sequence features were similar to those found in human adenoviruses, and open reading frames from this region could encode proteins similar to human adenovirus early region 1A and early region 1B proteins. DNAs from this region were tested in transient-expression assays in human and mouse cells were found to transactivate the human adenovirus type 5 early region 3 promoter fused to the chloramphenicol acetyltransferase gene. The data indicate structural and functional homologies between mouse adenovirus type 1 early region 1 and early region 1 of primate adenoviruses.
