cDNA and derived amino acid sequences of the sspaqr1 gene. Figure1A shows the hemolysin III motif identified using the NCBI Conserved Domain Database. The hemolysin III motif that is present in all PAQRs, extends from amino acid 270 to 495. Figure1B shows the cDNA and derived amino acid sequence of the sspaqr1 gene. Non-coding regions are given in lower case letters, coding regions and amino acids are given in upper case letters. Motif A, B and C are shaded yellow, blue-green, and green, respectively. Motif C includes part of the original sequence isolated in the yeast two-hybrid assay. The original sequence isolated using the yeast two-hybrid assay is underlined.
