The evolution of S100A7 in primates: a model of concerted and birth-and-death evolution
Immunogenetics, 2018The human S100A7 resides in the epidermal differentiation complex (EDC) and has been described as a key effector of innate immunity. In humans, there are five S100A7 genes located in tandem-S100A7A, S100A7P1, S100AL2, S100A7, and S100AP2. The presence of several retroelements in the S100A7A/S100A7P1 and S100A7/S100A7P2 clusters suggests that these ...

Concerted Evolution of Repetitive DNA Sequences in Eukaryotes
The Quarterly Review of Biology, 1995A large fraction, sometimes the largest fraction, of a eukaryotic genome consists of repeated DNA sequences. Copy numbers range from several thousand to millions per diploid genome. All classes of repetitive DNA sequences examined to date exhibit apparently general, but little studied, patterns of "concerted evolution." Historically, concerted ...

Concerted evolution in the GAPDH family of retrotransposed pseudogenes
Mammalian Genome, 1993In murine rodents the glyceraldehyde 3-phosphate dehydrogenase (GAPDH) multigene family includes more than 300 retroprocessed pseudogenes. Its single functional gene encodes GAPDH, an enzyme of glycolysis. Because of its manageable size, this family is a good model for the study of genome cohesion and evolution.

Evidence for Biased Gene Conversion in Concerted Evolution of Ribosomal DNA
Science, 1991Concerted evolution is the production and maintenance of homogeneity within repeated families of DNA. Two mechanisms—unequal crossing over and biased gene conversion—have been the principal explanations of concerted evolution. Concerted evolution of ribosomal DNA (rDNA) arrays is thought to be largely the result of unequal crossing over.

Gene conversion and concerted evolution in bacterial genomes
FEMS Microbiology Reviews, 2005Gene conversion is defined as the non-reciprocal transfer of information between homologous sequences. Despite methodological problems to establish non-reciprocity, gene conversion has been demonstrated in a wide variety of bacteria. Besides examples of high-frequency reversion of mutations in repeated genes, gene conversion in bacterial genomes has ...

Concerted Evolution of Human Interferon Alpha Genes
Journal of Interferon Research, 1983Multiple interferon (IFN) alpha genes characterize divergent animal species, yet human interferon alpha (HuIFN-alpha) genes are closely related in nucleotide sequence. Either the IFN-alpha genes derived from common ancestor sequences after divergence of these animals, or the HuIFN-alpha genes that have been studied underwent concerted evolution ...

Recombination and the concerted evolution of the murine MHC
Trends in Genetics, 1987Abstract The concerted evolution of the murine major histocompatibility complex (MHC) class I multigene family has resulted in the diversification as well as homogenezation of its member genes. Micro-recombinations between class I genes have resulted in the extreme diversification of the H-2 genes.

Ubiquitin genes as a paradigm of concerted evolution of tandem repeats
Journal of Molecular Evolution, 1987Ubiquitin is remarkable for its ubiquitous distribution and its extreme protein sequence conservation. Ubiquitin genes comprise direct repeats of the ubiquitin coding unit with no spacers. The nucleotide sequences of several ubiquitin repeats from each of humans, chicken, Xenopus, Drosophila, barley, and yeast have recently been determined. By analysis

Concerted evolution of satellite DNA in Sarcocapnos: a matter of time
Plant Molecular Biology, 2011SarkOne is a genus-specific satellite-DNA family, isolated from the genomes of the species of the genus Sarcocapnos. This satellite DNA is composed of repeats with a consensus length of 855 bp and a mean G+C content of 52.5%. We have sequenced a total of 189 SarkOne monomeric repeats belonging to a total of seven species of the genus Sarcocapnos.

Paradox lost: Concerted evolution and centromeric instability
BioEssays, 2022AbstractHomologous centromeres compete for segregation to the secondary oocyte nucleus at female meiosis I. Centromeric repeats also compete with each other to populate centromeres in mitotic cells of the germline and have become adapted to use the recombinational machinery present at centromeres to promote their own propagation. Repeats are not needed
