Chicken Ψ-amelogenin mRNA and deduced amino acid sequence. Insertion of four nucleotides (in red) in exon 2 leads to a reading frameshift, which changes the amino acids in the N-terminal region and results in a premature stop codon in exon 6 (in red). The intron-exon boundary and the intron size are also indicated.
