Figure 1


Fig. 1. The deduced amino acid sequences of At-sog, Pp-sog and Af-sog display high similarity to Drosophila Sog and vertebrate chordin. (A) HarrPlot analysis of the entire amino acid sequences of At-Sog and Drosophila Sog (Dm-Sog). The parameter `unit size to compare' was 8 and the parameter `dot plot scores' was 2. The four cysteine-rich domains characteristic of Sog/chordin (CRs 1-4) are indicated by black bars. (B) Amino acid sequence comparisons of At-Sog and the Sog/chordin protein of Pholcus (Pp), Artemia (Af), Anopheles (Ag), Drosophila (Dm) and Xenopus (Xl). Percentage identity and similarity (parentheses) were calculated for each of the CR1-4 domains and the region intervening between the CR1 and CR2 domains (INT) using the BLAST2 sequences tool. Accession numbers of the proteins used are as follows: Ag-Sog, EAA06317.3; Dm-Sog, AAA89117.1; Xl-chordin, AAC42222.
