Figure 4

Junctional diversity in avian atypical TCRδ CDR3 regions from different avian species. GenBank accession numbers are shown on the left of each sequence. P and N nucleotides are highlighted in black and grey, respectively. V-D-J germline sequences are at the top of the figure and indicated in bold. Gaps are shown with dots. Dashes indicate identity with the sequence at the top of each alignment for V and J gene segments. A. Adult zebra finch unique thymus cDNA sequences. D and J gene segments are indicated above the sequences. B. Unique V-D-J recombination sequences obtained from day 4 and day 21 chicken thymuses. Germline sequences are shown as described above. C. The 3′ end of the germ-line VHδ, the complete germ-line D, and complete germ-line J genes (un-recombined) from the chicken turkey genome assembles compared with the corresponding regions from the duck cDNA sequence (AF415216). D. Comparison of Dδ and Jδ germline gene segments from chicken, turkey, zebra finch (Dδ2 and Jδ2) and duck cDNA sequence. Conserved motif in the Jδ is highlighted in grey. Similar sequences between Dδ and Jδ gene segments are indicated in bold or underlined.
