Short homology repeats at the VDJ junctions. (A) Left, table showing the nucleotide sequences of the variable gene segments TRGV8 and TRGV10 (3′ ends, CDR3) and of the five joining gene segments TRGJ (J1/J2, JP, JP1, and JP2; 5′ ends, CDR3). Right, table showing the nucleotide sequences of the variable gene segments TRDV1 and TRDV2 and of the three diversity gene segments TRDD (D1, D2, D3). Short homology repeats are shown in red or in red and underlined. (B) Recombination using short homology repeats between TRGV8 and TRGJP1. Overlapping nucleotides are shown in red. (C) Recombination using short homology repeats between TRDV1 and TRDD3 and between TRDV2 and TRDD3. Overlapping nucleotides are shown in red (TRDV1-TRDD3) and in underlined red (TRDV2-TRDD3).
