Fish major histocompatibility complex genes: an expansion.
The advent of polymerase chain reaction technology has provoked a large amount of progress in the field of fish major histocompatibility complex (MHC) research. Many new teleost sequences have been reported in the last four years, including representatives of all classes of MHC genes. While the intron-exon structure of teleost MHC genes is now becoming clear, the organisation of the genes within the teleost MHC is still unclear. The sequences reported to date have been used for phylogenetic analysis and, due to their evolutionary position, are discussed in relation to hypotheses regarding the origin of the MHC. Teleost MHC gene sequences are also examined to see if conserved features of the both the nucleotide and amino acid sequences of higher vertebrate MHC genes are present. Differences in these features will reflect functional differences between teleost and mammalian MHC genes and may also have evolutionary implications.
