  1. ...Comparison of Human Chromosome 21 Conserved Nongenic Sequences (CNGs) With the Mouse and Dog Genomes Shows That Their Selective Constraint Is Independent of Their Genic Environment Emmanouil T. Dermitzakis 1 , 5 , Ewen Kirkness 2 , Scott Schwarz 3 , Ewan...
  2. ...Noncoding Sequences Conserved in a Limited Number of Mammals in the SIM2 Interval are Frequently Functional Kelly A. Frazer 1 , 3 , Heng Tao 1 , Kazutoyo Osoegawa 2 , Pieter J. de Jong 2 , Xiyin Chen 1 , Mark F. Doherty 1...
  3. ...of evolutionarily conserved sequences across gene-rich and gene-poor intervals is not known. Conserved sequences between humans and mice can be present either as a result of active conservation due to functional constraints or as a result of shared ancestry due to insufficient divergence time. Long human...
  4. ...be found upstream of the acceptor site. With the exception of these two cases, the branchpoint sequence was extremely conserved between mammals and chicken, showing no more than two mismatches, but often being identical. The position of the branch point has also been conserved; with only one exception...
  5. ...be exons that have not been annotated, but we suggest that this is relatively rare given that the gene annotations used included nearly 40,000 genes from multiple annotation sources. Additionally, the relatively high abundance of “nongenicconserved sequences in mammalian s has been previously documented...
  6. ...evidence for strong constraints in intergenic DNA by inferring that there are similar numbers of conserved bases in intergenic sequences as in introns (22%–26%). Halligan et al. (2004) showed that this fraction may be as high as ∼44% in an analysis of 119 intergenic DNA fragments flanking known genes...
  7. ...identified many interspersed conserved sequences. For example, Bejerano et al. (2004b) listed ∼5000 kinds of sequence categories, each of which is conserved among mammals and is present in more than one copy in the human . The detailed functions of most of these regions have not been elucidated. Eukaryotic s...
  8. ...-HMM). PhastCons works by fitting a phylo-HMM to the data by maximum likelihood, subject to constraints designed to calibrate the model across species groups, and then predicting conserved elements based on this model. The predicted elements cover roughly 3%–8% of the human genome (depending on the details...
  9. ...( Kleinjan and van Heyningen 2005 ). Identifying putative CRMs computationally relies on phylogenetic footprinting (for overview, see Ureta-Vidal et al. 2003 ) with sequence conservation implying functional constraint, although the confidence of such predictions depends on the evolutionary distance between...
  10. .... 2010; Duan et al. 2019), with myriad dispensable genes responsible for agronomic traits and human diseases uncovered (Yu et al. 2022). In contrast to microorganisms, mammals typically have larger size and less flexibility, where genes in the usual sense constitute a minor fraction of total sequences...
