Highly divergent dimorphic alleles of the proteasome subunit beta type-8 (PSMB8) gene of the bichir Polypterus senegalus: implication for evolution of the PSMB8 gene of jawed vertebrates.

Abstract excerpt

The proteasome subunit beta type-8 (PSMB8) gene encodes a catalytic subunit of the immunoproteasome, which is involved in the generation of peptides presented by MHC class I molecules. To date, highly diverged dichotomous alleles of PSMB8 have been reported in Oryzias species (actinopterygian teleosts) and Xenopus species (sarcopterygian amphibians). These dimorphic alleles share a similar substitution...
