Figure 2.

HHP1-derived protein sequence. Translation of the longest ORF of the HHP1 gene is shown from the presumed initiator methionine. Protein sequences unambiguously identified by direct sequencing of the intact polypeptide and the fragment generated by cyanogen bromide are underlined. The amino-terminal chromodomain and carboxy-terminal chromoshadow domain are shown in bold. The positions of two potential phosphorylation sites for Cdc-2 kinase were indicated by asterisks.
