11. Evolution and Pharmacology of Neuropeptide Y Receptors, Implications for vertebrate genome duplications
Sammanfattning : The Y receptors comprise a family of evolutionarily related receptors belonging to the superfamily of G-protein coupled receptors (GPCR). Their natural ligands are in mammals neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP). LÄS MER
12. Evolutionary Genomics of Nematode-Trapping Fungi
Sammanfattning : Nematode-trapping fungi are ubiquitous, soil-living organisms with the ability to infect and kill nematodes. These fungi have developed specialized infection structures for the capture of nematodes. LÄS MER
13. Defining human adaptive immune gene diversity
Sammanfattning : The lymphocytes (B and T cells) of the adaptive immune system undergo variable (V), diversity (D), and junctional (J) gene recombination, resulting in highly diverse antigen receptor repertoires capable of recognizing a wide variety of invading pathogens. The B cell receptor (BCR) contains two identical heavy and light chains. LÄS MER
14. Reconciling gene family evolution and species evolution
Sammanfattning : Species evolution can often be adequately described with a phylogenetic tree. Interestingly, this is the case also for the evolution of homologous genes; a gene in an ancestral species may – through gene duplication, gene loss, lateral gene transfer (LGT), and speciation events – give rise to a gene family distributed across contemporaneous species.

15. The Gene Repertoire of G protein-coupled Receptors : New Genes, Phylogeny, and Evolution
Sammanfattning : The superfamily of G protein-coupled receptors (GPCRs) is one of the largest protein families of mammalian genomes and can be divided into five main families; Glutamate, Rhodopsin, Adhesion, Frizzled, and Secretin. GPCRs participate in most major physiological functions, contributing to the fact that they are important targets in drug discovery. LÄS MER
