FIGURE 4.

(A) Proximal promoter region of TYR gene. Positions +1 were assigned to the translation initiation site (ATG codon). Regulatory elements are aligned with its consensus sequence in black blocks and named underneath. Numbers above the elements indicate relative positions. Red squares indicate the location of the SNPs found in llamas and the repeated elements are underlined. (B) TYR LCR region. Nucleotide positions (from 1 to 646) are indicated in black above the sequence. Number 1 was arbitrarily designed to the first nucleotide showed. Boxes A and B are aligned to the ones of mouse and human (X76647 and AY180962) and the variation found in llamas is squared in red color.
