Molecular characteristic of the three CcPRF genes. a-c cDNA and deduced amino acid sequences. CcPRF1, CcPRF2 and CcPRF3 are shown in a, b and c, respectively. The translation start codon ATG and termination codons TGA or TAA are shown in red. The signal peptides are boxed, and the MACPF and CalB domains are highlighted in light gray and blue, respectively. In addition, the polyadenylation signal (aataaa) and poly (a) tail are in bold and underlined. d Domain structures of three CcPRF proteins. The signal peptide (black), MACPF (brown) and CalB (darkgray) are depicted in different colors, and the numbers refer to the length of the amino acid sequences. e Amino acid (black) and nucleic acid (green) identities among the three CcPRFs. f 3-Dimensional protein structures were predicted using the SWISS-MODEL server, with selection of the model based on the best C-score
