Some asymptotic properties of duplication graphs
, 2003 Duplication graphs are graphs that grow by duplication of existing vertices, and are important models of biological networks, including protein-protein interaction networks and gene regulatory networks.

Analysis of the Size of the Carcinoembryonic Antigen (CEA) Gene Family [PDF]
, 1989 Five members of the human CEA gene family [human pregnancy-specific β1-glycoprotein (PSβG), hsCGM1, 2, 3 and 4] have been isolated and identified through sequencing the exons containing their N-terminal domains.

Homeobox Gene Duplication and Divergence in Arachnids
Molecular Biology and Evolution, 2018 Homeobox genes are key toolkit genes that regulate the development of metazoans and changes in their regulation and copy number have contributed to the evolution of phenotypic diversity. We recently identified a whole genome duplication (WGD) event that occurred in an ancestor of spiders and scorpions (Arachnopulmonata), and that many homeobox genes ...

Gene Duplications in the Genomes of Staphylococci and Enterococci [PDF]
Frontiers in Molecular Biosciences, 2020 Gene duplications are a feature of bacterial genomes. In the present work we analyze the extent of gene duplications in the genomes of three microorganisms that belong to the Firmicutes phylum and that are etiologic agents of several nosocomial infections: Staphylococcus aureus, Enterococcus faecium, and Enterococcus faecalis.

Evolutionary history of the UCP gene family: gene duplication and selection [PDF]
BMC Evol. Biol. 8 (2008) 306, 2008 BACKGROUND: The uncoupling protein (UCP) genes belong to the superfamily of electron transport carriers of the mitochondrial inner membrane. Members of the uncoupling protein family are involved in thermogenesis and determining the functional evolution of UCP genes is important to understand the evolution of thermo-regulation in vertebrates.

BMC Bioinformatics, 2012 Background Evolutionary methods are increasingly challenged by the wealth of fast growing resources of genomic sequence information. Evolutionary events, like gene duplication, loss, and deep coalescence, account more then ever for incongruence between ...

Modes of gene duplication contribute differently to genetic novelty and redundancy, but show parallels across divergent angiosperms. [PDF]
PLoS ONE, 2011 BACKGROUND: Both single gene and whole genome duplications (WGD) have recurred in angiosperm evolution. However, the evolutionary effects of different modes of gene duplication, especially regarding their contributions to genetic novelty or redundancy ...

Influence of gene copy number on self-regulated gene expression [PDF]
, 2016 Using an analytically solvable stochastic model, we study the properties of a simple genetic circuit consisting of multiple copies of an self-regulating gene. We analyse how the variation in gene copy number and the mutations changing the auto-regulation strength affect the steady-state distribution of protein concentration.

Gene Duplication to Reveal Adaptation Clue of Plant to Environmental Stress: a Case Study of NBS-LRR Genes in Soybean [PDF]
, 2016 Genes responsive to the environmental stresses which are retained after small scale duplication are part of plant genome duplication. However, information of duplicated genes that could be adaptive to environmental changes in plant is limited.

The shape of human gene family phylogenies
BMC Evolutionary Biology, 2006 Background The shape of phylogenetic trees has been used to make inferences about the evolutionary process by comparing the shapes of actual phylogenies with those expected under simple models of the speciation process.
