摘要：
Apart from its intrinsic interest, the elucidation of evolutionary relationships among proteins can provide useful structural and functional insights. Recent progress towards understanding the sequences that are evolutionarily conserved among diverse eukaryotes ('ancient conserved regions') include: the identification of several new ancient conserved regions; the development of more sensitive methods for detecting distant sequence relationships; and the discoveries (from analysis of new sets of genes from genome sequencing projects) that most ancient conserved regions are already represented among known proteins, and that a majority of genes do not contain such regions. These ideas are illustrated in the context of an updated analysis of the ancient conserved regions present in a 'typical' eukaryotic genomic sequence, yeast chromosome III.
