MSM/Ms is an inbred strain derived from the Japanese wild mouse, Mus musculus molossinus. It is believed that subspecies molossinus has contributed substantially to the genome constitution of common laboratory strains of mice, although the majority of their genome is derived from the west European M. m. domesticus. Information on the molossinus genome is(More)
Gene conversion is considered to play important roles in the formation of genomic makeup such as homogenization of multigene families and diversification of alleles. We devised two statistical tests on quartets for detecting gene conversion events. Each "quartet" consists of two pairs of orthologous sequences supposed to have been generated by a duplication(More)
Homogenization of duplicated genes is an important factor for gene family evolution. In the previous study, we developed a method, named 4-2-4 here, to detect partial homogenization with high sensitivity and high specificity using quartets. A quartet is a set of four genes generated by a duplication event and the subsequent speciation of two closely related(More)
Duplogs, or intraspecies paralogs, constitute the important portion of eukaryote genomes and serve as a major source of functional innovation. We conducted detailed analyses of recently emerged animal duplogs. Genome data of three vertebrate species (Homo sapiens, Mus musculus, and Danio rerio), Caenorhabditis elegans, and two Drosophila species (Drosophila(More)
Gasdermin (Gsdm) was originally identified as a candidate causative gene for several mouse skin mutants. Several Gsdm-related genes sharing a protein domain with DFNA5, the causative gene of human nonsyndromic hearing loss, have been found in the mouse and human genomes, and this group is referred to as the DFNA5-Gasdermin domain family. However, our(More)
Insertions and deletions (indels) account for more nucleotide differences between two related DNA sequences than substitutions do, and thus it is imperative to develop a method to reliably calculate the occurrence probabilities of sequence alignments via evolutionary processes on an entire sequence. Previously, we presented a perturbative formulation that(More)
Insertions and deletions (indels) account for more nucleotide differences between two related DNA sequences than substitutions do, and thus it is imperative to develop a stochastic evolutionary model that enables us to reliably calculate the probability of the sequence evolution through indel processes. Recently, indel probabilistic models are mostly based(More)
Reconstruction of multiple sequence alignments (MSAs) is a crucial step in most homology-based sequence analyses, which constitute an integral part of computational biology. To improve the accuracy of this crucial step, it is essential to better characterize errors that state-of-the-art aligners typically make. For this purpose, we here introduce two tools:(More)
