  1. ...regarding their contribution to protein plasticity. Good candidates for illuminating these older exonization processes are the retroposed mammalian-wide interspersed repeat (MIR) elements. MIR elements amplified ∼130 million years ago (Mya), and they number, for example, in human, ∼368,000 discernible...
  2. ...and fish than of mammals. The platypus is a specialized semiaquatic carnivore that displays several unique features. Its leathery bill is equipped with specialized neurons, which serve as electrosensors, and male platypuses have spikes on their hind legs, which are used in an elaborate venom delivery...
  3. ...Retroposed New Genes Out of the X in Drosophila Esther Betrán 1 , Kevin Thornton 2 , and Manyuan Long 1 , 2 , 3 1 Department of Ecology and Evolution; 2 Committee on Genetics, The University of Chicago, Chicago, Illinois 60637, USA...
  4. ...Bird-like sex chromosomes of platypus imply recent origin of mammal sex chromosomes Frédéric Veyrunes 1 , 2 , 6 , Paul D. Waters 1 , 6 , 7 , Pat Miethke 1 , Willem Rens 2 , Daniel McMillan 1 , Amber E. Alsop 1 , Frank...
  5. ...through a bite, as do snakes and shrews, male platypuses have venomous spurs on each hind leg. The platypus genome sequence provides a unique opportunity to unravel the evolutionary history of many of these interesting features. While searching the platypus genome for the sequences of antimicrobial...
  6. ...of all snoRNA copies (with the extreme case of the platypus, which was reported to have more than 40,000 full or truncated snoRNA copies, most being located in suboptimal genomic context) (Schmitz et al. 2008).Another interesting avenue following snoRNA integration in a locus is the development of new...
  7. ...Retroposed Copies of the HMG Genes: A Window to Genome Dynamics Liora Z. Strichman-Almashanu 1 , Michael Bustin 2 , and David Landsman 1 , 3 1Computational Biology Branch, National Center for Biotechnology Information, National Library...
  8. ...in misregulation of expression of ∼50% of transcribed protein-coding genes, probably as a secondary effect of accumulation of various noncoding RNA species. Finally, cells expressing mutant DIS3 accumulated snoRNA precursors, which correlated with a strong PAR-CLIP signal, indicating that DIS3 is the main snoRNA...
  9. ...elements correspond to functional centromeric sequences. We analyzed genome datasets from six species of mammals representing the diversity of the mammalian lineage, namely, horse, dog, elephant, armadillo, opossum, and platypus. We define candidate monomer satellite repeats and demonstrate centromeric...
  10. ...show that species-specific expansions previously observed in only eight species were prevalent throughout mammalian evolution, resulting in “semi-private” V1R repertoires for most mammals. The largest families are found in mouse and platypus, whose V1R repertoires have been published previously...
