Predicted amino acid sequence resulting from nonsense mutations. Consensus sequence was determined according to results of alignment of 20 different species of RPS19 performed with MultAlin (Corpet. F., 1988). ! stands for any of Isoleucine or Valine, % for any of Phenylalanine or Tyrosine, and # for any of Aparagine or Aspartic acid or glutamine or glycine. Upper case letters indicate high consensus values (>90%), and lower case letters indicate low consensus values (between 50% and 90%). Numbers indicate position along human amino acid sequence. Bold letters in the human wild-type RPS19 sequence indicate the high consensus values.
