Ciezarek A, Osbourne O, Shipley ON, et al., Diversification of characteristics related to regional endothermy in Thunnus tunas, Molecular Biology and Evolution, ISSN: 1537-1719
Birds, mammals, and certain fishes, including tunas, opahs and lamnid sharks, are endothermic, conserving internally generated, metabolic heat to maintain body or tissue temperatures above that of the environment. Bluefin tunas, among the most threatened, but commercially important, fishes worldwide are renowned regional endotherms, maintaining elevated temperatures of the oxidative locomotor muscle, viscera, brain and eyes, and occupying cold, productive high-latitude waters. Less cold-tolerant tuna, such as yellowfin, by contrast, remain in warm-temperate to tropical waters year-round, reproducing more rapidly than temperate bluefin tuna. Thereby, they are more resilient to fisheries, whereas bluefins have declined steeply. Despite the importance of these traits to not only fisheries, but response to climate change, little is known of the genetic processes underlying the diversification of tuna. In collecting and analysing sequence data across 29,556 genes, we found that parallel selection on standing genetic variation has driven the evolution of endothermy in bluefin tunas. This includes two shared substitutions in genes encoding glycerol-3 phosphate dehydrogenase, an enzyme which underlies thermogenesis in bumblebees and mammals, as well as four genes involved in the Krebs cycle, oxidative phosphorylation, β-oxidation and superoxide removal. Using phylogenetic techniques, we further illustrate that the eight Thunnus species are genetically distinct, but found evidence of mitochondrial genome introgression across two species. Phylogeny-based metrics highlight conservation needs for some of these species.

David A, Sternberg MJ, 2015, The contribution of missense mutations in core and rim residues of protein-protein interfaces to human disease., Journal of Molecular Biology, Vol: 427, Pages: 2886-2898, ISSN: 1089-8638
Missense mutations at protein-protein interaction (PPIs) sites, called interfaces, are important contributors to human disease. Interfaces are non-uniform surface areas characterized by two main regions, 'core' and 'rim', which differ in terms of evolutionary conservation and physico-chemical properties. Moreover, within interfaces, only a small subset of residues ('hot spots') is crucial for the binding free energy of the protein-protein complex. We performed a large-scale structural analysis of human single amino acid variations (SAVs) and demonstrated that disease-causing mutations are preferentially located within the interface core, as opposed to the rim (p< 0.01). In contrast, the interface rim is significantly enriched in polymorphisms, similar to the remaining non-interacting surface. Energetic hot spots tend to be enriched in disease-causing mutations compared to non-hot spots (p=0.05), regardless of their occurrence in core or rim residues. For individual amino acids, the frequency of substitution into a polymorphism or disease-causing mutation differed to other amino acids and was related to its structural location, as was the type of physico-chemical change introduced by the SAV. In conclusion, this study demonstrated the different distribution and properties of disease-causing SAVs and polymorphisms within different structural regions and in relation to the energetic contribution of amino acid in protein-protein interfaces, thus highlighting the importance of a structural system biology approach for predicting the effect of SAVs.
Kelley LA, Sternberg MJ, 2015, Partial protein domains: evolutionary insights and bioinformatics challenges., Genome Biology, Vol: 16, Pages: 100-100, ISSN: 1474-760X
Protein domains are generally thought to correspond to units of evolution. New research raises questions about how such domains are defined with bioinformatics tools and sheds light on how evolution has enabled partial domains to be viable.
Kelley LA, Mezulis S, Yates CM, et al., 2015, The Phyre2 web portal for protein modeling, prediction and analysis., Nature Protocols, Vol: 10, Pages: 845-858, ISSN: 1754-2189
Phyre2 is a suite of tools available on the web to predict and analyze protein structure, function and mutations. The focus of Phyre2 is to provide biologists with a simple and intuitive interface to state-of-the-art protein bioinformatics tools. Phyre2 replaces Phyre, the original version of the server for which we previously published a paper in Nature Protocols. In this updated protocol, we describe Phyre2, which uses advanced remote homology detection methods to build 3D models, predict ligand binding sites and analyze the effect of amino acid variants (e.g., nonsynonymous SNPs (nsSNPs)) for a user's protein sequence. Users are guided through results by a simple interface at a level of detail they determine. This protocol will guide users from submitting a protein sequence to interpreting the secondary and tertiary structure of their models, their domain composition and model quality. A range of additional available tools is described to find a protein structure in a genome, to submit large number of sequences at once and to automatically run weekly searches for proteins that are difficult to model. The server is available at http://www.sbg.bio.ic.ac.uk/phyre2. A typical structure prediction will be returned between 30 min and 2 h after submission.

Irimia M, Weatheritt RJ, Ellis JD, et al., 2014, A Highly Conserved Program of Neuronal Microexons Is Misregulated in Autistic Brains, Cell, Vol: 159, Pages: 1511-1523, ISSN: 0092-8674
Alternative splicing (AS) generates vast transcriptomicand proteomic complexity. However, whichof the myriad of detected AS events provide importantbiological functions is not well understood.Here, we define the largest program of functionallycoordinated, neural-regulated AS described to datein mammals. Relative to all other types of AS withinthis program, 3-15 nucleotide ‘‘microexons’’ displaythe most striking evolutionary conservation andswitch-like regulation. These microexons modulatethe function of interaction domains of proteinsinvolved in neurogenesis. Most neural microexonsare regulated by the neuronal-specific splicing factornSR100/SRRM4, through its binding to adjacentintronic enhancer motifs. Neural microexons arefrequently misregulated in the brains of individualswith autism spectrum disorder, and this misregulationis associated with reduced levels of nSR100.The results thus reveal a highly conserved programof dynamic microexon regulation associated withthe remodeling of protein-interaction networks duringneurogenesis, the misregulation of which islinked to autism.
