Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The role of genomic Copy Number Variation (CNV) in osteoporosis [PDF]

, 2012
Copy number variation (CNV) is a relatively novel source of genetic variation, involving the duplication or deletion of segments of genomic DNA (gDNA) sequence, thereby changing the original number of DNA copies.

Genetic copy number variation and general cognitive ability.

PLoS ONE, 2012
Differences in genomic structure between individuals are ubiquitous features of human genetic variation. Specific copy number variants (CNVs) have been associated with susceptibility to numerous complex psychiatric disorders, including attention-deficit ...

MONTAGE: a new tool for high-throughput detection of mosaic copy number variation

BMC Genomics, 2021
Background Not all cells in a given individual are identical in their genomic makeup. Mosaicism describes such a phenomenon where a mixture of genotypic states in certain genomic segments exists within the same individual.

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Modeling copy number variation in the genomic prediction of maize hybrids

, 2018
Non-additive effects resulting from the actions of multiple loci may influence trait variation in single-cross hybrids. In addition, complementation of allelic variation could be a valuable contributor to hybrid genetic variation, especially when ...

Elusive copy number variation in the mouse genome.

PLoS ONE, 2010
BackgroundArray comparative genomic hybridization (aCGH) to detect copy number variants (CNVs) in mammalian genomes has led to a growing awareness of the potential importance of this category of sequence variation as a cause of phenotypic variation.

Human subtelomeric copy number variations [PDF]

Cytogenetic and Genome Research, 2008
Copy number variation is a defining characteristic of human subtelomeres. Human subtelomeric segmental duplication regions (‘Subtelomeric Repeats’) comprise about 25% of the most distal 500 kb and 80% of the most distal 100 kb in human DNA. Huge allelic disparities seen in subtelomeric DNA sequence content and organization are postulated to have an ...
