Shown below is an amino acid sequence alignment between two human zinc finger proteins. Conserved amino acid sequences are marked by strings of formula_1 on the third line of the sequence alignment. As can be seen from this alignment, these two proteins contain a number of conserved amino acid sequences (represented by identical letters aligned between the two sequences).
