Figure 5.

Comparison of amino acid sequence from the beginning of clone S26 (from the fusion joint with GFP) with chromodomains from Drosophila melanogaster HP1 (GenBank accession no. M57574M57574), a human homolog of HP1 (accession no. L07515L07515), and mouse Modifier 1 protein (accession no. P23197P23197). Residues conserved among all four proteins are shown in bold. The alignment of the latter three sequences is based on that of Aasland and Stewart (24) and further details and comparisons with other chromodomain proteins can be found therein.
