Evolutionary History Reconstruction for Mammalian Complex 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 کاملSimultaneous History Reconstruction for Complex Gene Clusters in Multiple Species
Genomic intervals that contain a cluster of similar genes are of extreme biological interest, but difficult to sequence and analyze. One goal for interspecies comparisons of such intervals is to reconstruct a parsimonious series of duplications, deletions, and speciation events (a putative evolutionary history) that could have created the contemporary clusters from their last common ancestor. W...

متن کاملRevealing Mammalian Evolutionary Relationships by Comparative Analysis of Gene Clusters
Many software tools for comparative analysis of genomic sequence data have been released in recent decades. Despite this, it remains challenging to determine evolutionary relationships in gene clusters due to their complex histories involving duplications, deletions, inversions, and conversions. One concept describing these relationships is orthology. Orthologs derive from a common ancestor by ...
متن کاملComplex Evolutionary History of the Mammalian Histone H1.1–H1.5 Gene Family
H1 is involved in chromatin higher-order structure and gene regulation. H1 has a tripartite structure. The central domain is stably folded in solution, while the N- and C-terminal domains are intrinsically disordered. The terminal domains are encoded by DNA of low sequence complexity, and are thus prone to short insertions/deletions (indels). We have examined the evolution of the H1.1-H1.5 gene...
