Abstract
The systematic comparison of genomic sequences from different organisms represents a central focus of contemporary genome analysis. Comparative analyses of vertebrate sequences can identify coding and conserved non-coding regions, including regulatory elements, and provide insight into the forces that have rendered modern-day genomes. As a complement to whole-genome sequencing efforts, we are sequencing and comparing targeted genomic regions in multiple, evolutionarily diverse vertebrates. Here we report the generation and analysis of over 12 megabases (Mb) of sequence from 12 species, all derived from the genomic region orthologous to a segment of about 1.8 Mb on human chromosome 7 containing ten genes, including the gene mutated in cystic fibrosis. These sequences show conservation reflecting both functional constraints and the neutral mutational events that shaped this genomic region. In particular, we identify substantial numbers of conserved non-coding segments beyond those previously identified experimentally, most of which are not detectable by pair-wise sequence comparisons alone. Analysis of transposable element insertions highlights the variation in genome dynamics among these species and confirms the placement of rodents as a sister group to the primates.

Recio JA, Páez JG, Maskeri B, Loveland M, Velasco JA, Notario V. Both normal and transforming PCPH proteins have guanosine diphosphatase activity but only the oncoprotein cooperates with Ras in activating extracellular signal-regulated kinase ERK1.

Abstract
Previous reports from our laboratory described the activation of the PCPH gene into the PCPH oncogene (mt-PCPH, reported previously as Cph) by a single point mutational deletion. As a consequence, the mt-PCPH oncoprotein is a truncated form of the normal PCPH protein. Although both proteins have ribonucleotide diphosphate-binding activity, only mt-PCPH acted synergistically with a human H-Ras oncoprotein to transform murine NIH3T3 fibroblasts. We report here the expression of the PCPH and mt-PCPH proteins in Escherichia coli and the finding that the purified bacterial recombinant proteins have intrinsic guanosine diphosphatase (GDPase) activity. However, expression of the Syrian hamster PCPH and mt-PCPH proteins in haploid yeast strains engineered to be GDPase deficient by targeted disruption of the single GDA1 allele did not complement their glycosylation-disabled phenotype, suggesting the existence of significant functional differences between the mammalian and yeast enzymes. Results from transient cotransfections into NIH3T3, COS-7, or 293T cells indicated that, in mammalian cells, both PCPH and mt-PCPH cause an overall down-regulation of the stimulatory effect of epidermal growth factor or the activated ras or raf oncogenes on the Ras/mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) signaling pathway. However, despite this overall negative regulatory role on Ras signaling, mt-PCPH, but not PCPH, cooperated with the Ras oncoprotein to produce a prolonged stimulation of the phosphorylation of ERK1 but had no effect on the phosphorylation levels of ERK2. These results represent a clear difference between the mechanisms of action of PCPH and mt-PCPH and suggest that the ability to cause a sustained activation of ERK1 may be an important determinant of the transforming activity of mt-PCPH.
