Homoplasy in genome-wide analysis of rare amino acid replacements: the molecular-evolutionary basis for Vavilov's law of homologous series [PDF]

open access: yes, 2008
Background Rare genomic changes (RGCs) that are thought to comprise derived shared characters of individual clades are becoming an increasingly important class of markers in genome-wide phylogenetic studies.

A clustered set of three Sp-family genes is ancestral in the Metazoa: evidence from sequence analysis, protein domain structure, developmental expression patterns and chromosomal location

open access: yesBMC Evolutionary Biology, 2010
Background The Sp-family of transcription factors are evolutionarily conserved zinc finger proteins present in many animal species. The orthology of the Sp genes in different animals is unclear and their evolutionary history is therefore controversially ...

Alternative NAD(P)H dehydrogenase and alternative oxidase: proposed physiological roles in animals [PDF]

open access: yes, 2019
The electron transport systems in mitochondria of many organisms contain alternative respiratory enzymes distinct from those of the canonical respiratory system depicted in textbooks.

A conserved cluster of three PRD-class homeobox genes (homeobrain, rx and orthopedia) in the Cnidaria and Protostomia

open access: yesEvoDevo, 2010
Background Homeobox genes are a superclass of transcription factors with diverse developmental regulatory functions, which are found in plants, fungi and animals.

An evaluation of the evolution of the gene structure of dystroglycan [PDF]

open access: yes, 2017
BACKGROUND: Dystroglycan (DG) is an adhesion receptor complex composed of two non-covalently associated subunits, transcribed from a single gene. The extracellular α-DG is highly and heterogeneously glycosylated and binds with high affinity to laminins ...

Apicortin defines the Plasmodium apical conoid body but is dispensable for the parasite life cycle

open access: yesLife Science Alliance
Apicortin shapes the Plasmodium cytoskeleton at the apical end without impacting transmission. Apicomplexan parasites such as Plasmodium spp. and Toxoplasma gondii possess unique tubulin-based structures, including subpellicular microtubules and apical ...

Local structural alignment of RNA with affine gap model [PDF]

open access: yes, 2010
Predicting new non-coding RNAs (ncRNAs) of a family can be done by aligning the potential candidate with a member of the family with known sequence and secondary structure.

On an Evolutionary Foundation of Neuroeconomics [PDF]

open access: yes
Neuroeconomics focuses on brain imaging studies mapping neural responses to choice behavior. Economic theory is concerned with choice behavior but it is silent on neural activities.

Genomic organization of eukaryotic tRNAs

open access: yesBMC Genomics, 2010
Background Surprisingly little is known about the organization and distribution of tRNA genes and tRNA-related sequences on a genome-wide scale. While tRNA gene complements are usually reported in passing as part of genome annotation efforts, and ...
