Figure 3. CNGB1 protein alignments.
A) CNGB1 amino acid alignment of the normal and affected dogs. The p.Tyr889Serfs*5 mutation in the affected dog results in a loss of a significant part of the C-terminus of the protein and probable NMD of the CNGB1 mRNA B) CNGB1 sequence alignment between different vertebrates. The mutation is located in a highly conserved region across species. The arrows mark the first mutated amino acid caused by the frameshift and the premature stop codon.
