Figure 1. Schematic diagram of RS1 protein. The following abbreviations were used: LS represents leader sequence (23 amino acids (AAs)), Rs1D represents Rs1 domain (39 AAs), DD represents discoidin domain (157 AAs), and there is a five AA segment present on the C-terminal side of the DD. The red line marks the position of the putative premature stop codon at the beginning of exon 3.
