On an evolutionary time scale, polymorphic alleles are believed to have a short life, persisting at most tens of millions of years even under long-term balancing selection. Here, we report highly diverged trans-species dimorphism of the proteasome...

It has been generally thought that a tiny freshwater fish, medaka (Oryzias latipes), has expanded its habitat into the Japanese archipelago as wet-rice cultivation spread across the region, and hence the distribution of medaka should be a matter o...

The proteasome subunit beta-type 8 (PSMB8) gene in the jawed vertebrate MHC genomic region encodes a catalytic subunit of the immunoproteasome involved in the generation of peptides to be presented by the MHC class I molecules. A teleost, the meda...

Sequence comparison of the medaka, Oryzias latipes, major histocompatibility complex (MHC) class I region between two inbred strains, the HNI (derived from the Northern Population) and the Hd-rR (from the Southern Population), revealed a similar t...

The major histocompatibility complex (MHC) is present at a single chromosomal locus of all jawed vertebrate analyzed so far, from sharks to mammals, except for teleosts whose orthologs of the mammalian MHC-encoded genes are dispersed at several ch...
