  • a Searches of the literature and of the Saccharomyces database ( were used to identify candidate genes. The resulting amino acid sequences were used to find orthologues in the Neurospora predicted protein database. Where this approach yielded nothing, a TBLASTN search of the whole Neurospora genome sequence was performed, thus allowing us to locate msh-4. The amino acid sequence of the best match for each gene was used to search the Swiss Prot + TrEMBL nonredundant protein databases. For msh-4, the Neurospora nucleotide sequence was used in a BLASTS search against Swiss Prot + TrEMBL. S. cerevisiae genes with no Neurospora orthologue were used to search Swiss Prot + TrEMBL or the human genome protein database (
