Reconstructing the evolutionary history of microcephalin, a gene controlling human brain size.
The defining process in the evolution of primates and particularly humans is the dramatic expansion of the brain. While many types of genes could potentially contribute to this process, genes that specifically regulate brain size during development may be especially relevant. Here, we examine the evolution of the microcephalin gene, whose null mutation in humans causes primary microcephaly, a c...
متن کاملEvolutionary History of a Gene Controlling Brain Size
When James Watson and Francis Crick reported the structure of DNA in 1953, the mechanism of inheritance was instantly apparent. The complementary pairing of the DNA bases in the double helix, the pair famously wrote, “immediately suggests a possible copying mechanism for the genetic material.’’ The structure helped explain one of the central problems of modern biology: how does genetic material...
متن کاملMolecular evolution of microcephalin, a gene determining human brain size.
Microcephalin gene is one of the major players in regulating human brain development. It was reported that truncated mutations in this gene can cause primary microcephaly in humans with a brain size comparable with that of early hominids. We studied the molecular evolution of microcephalin by sequencing the coding region of microcephalin gene in humans and 12 representative non-human primate sp...
متن کاملReconstructing the Evolutionary History of Complex Human Gene Clusters
Clusters of genes that evolved from single progenitors via repeated segmental duplications present significant challenges to the generation of a truly complete human genome sequence. Such clusters can confound both accurate sequence assembly and downstream computational analysis, yet they represent a hotbed of functional innovation, making them of extreme interest. We have developed an algorith...
متن کاملReconstructing the Evolutionary History of Transposable Elements
The impact of transposable elements (TEs) on genome structure, plasticity, and evolution is still not well understood. The recent availability of complete genome sequences makes it possible to get new insights on the evolutionary dynamics of TEs from the phylogenetic analysis of their multiple copies in a wide range of species. However, this source of information is not always fully exploited. ...
