Origin and evolution of laminin gene family diversity.
Laminins are a family of multidomain glycoproteins that are important contributors to the structure of metazoan extracellular matrices. To investigate the origin and evolution of the laminin family, we characterized the full complement of laminin-related genes in the genome of the sponge, Amphimedon queenslandica. As a representative of the Demospongiae, a group consistently placed within the e...
متن کاملGene Family: Structure, Organization and Evolution
Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...
متن کاملOrigin and Evolution of the Sponge Aggregation Factor Gene Family
Although discriminating self from nonself is a cardinal animal trait, metazoan allorecognition genes do not appear to be homologous. Here, we characterize the Aggregation Factor (AF) gene family, which encodes putative allorecognition factors in the demosponge Amphimedon queenslandica, and trace its evolution across 24 sponge (Porifera) species. The AF locus in Amphimedon is comprised of a clus...
متن کاملOrigin and hydrogeochemical evolution of Azarshahr travertine springs, NW Iran
1-Introduction Travertines are limestones that form where hot groundwaters rich in calcium and bicarbonate emerge at springs. Travertines cover a large area southwest of Azarshahr (East Azarbaijan province), in some parts of which active springs are currently settling travertine. One of the main questions about travertine springs is their origin, as well as the secondary processes that have ch...
متن کاملOrigin, Diversity, Expansion History, and Functional Evolution of the Plant Receptor-Like Kinase/Pelle Family
The RLK/Pelle gene family is one of the largest gene families in plants with several hundred to more than a thousand members, but only a few family members exist in animals. This unbalanced distribution indicates a rather dramatic expansion of this gene family in land plants. In this chapter we review what is known about the RLK/Pelle family’s origin in eukaryotes, its domain content evolution,...
