Repeats present in CagA are a site for tyrosine phosphorylation. Within the cagA gene, duplication of sequence motifs in the 5′-end region assembled into a repeat at nucleotide position 3406. The anatomy of a repeat is based on three domains: D1, D2, and D3. Repeats are 102 bp causing an increment in size of the protein of 4 kDa. The EPIYA motifs are shown.
