Sequence alignment of mouse Pw1 (GenBank accession no. U48804) and human PEG3 amino acid sequence (GenBank accession no. 90336). The upper sequence represents the mouse Pw1 and the lower sequence represents the partial human PEG3 amino acid sequence derived from a genomic fragment of one of Peg3cosmids (F14378). The partial human PEG3 cDNA clone (GenBank accession no. H08927) contains the region corresponding to the last two fingers and 3′ UTR of human PEG3. Zinc finger regions are bold, and finger number and proline repeat regions are indicated atright. Sequence identity (vertical line), conservative substitution (colon), and amino acids with similar properties (dot) are indicated. The two sequences are aligned for maximal match by the BestFit program of the Genetics Computer Group package. We believe that mouse Pw1 and Peg3 represent the same gene, and, for the overall comparison analysis, mouse Pw1 was used instead ofPeg3 because its complete sequence is publicly available.
