Collier de Perles: Human TRA V-J REGION

Human rearranged TRBV6-5 - TRBD2 - TRBJ2-7

[5.6.14]

Legend:

Amino acids are shown in the one-letter abbreviation.
Hydrophobic amino acids (hydropathy index with positive value) and Tryptophan (W) found at a given position in more than 50 % of analysed Ig and TcR sequences are shown in blue.
All Proline (P) are shown in yellow.
The CDR-IMGT are limited by amino acids shown in squares, which belong to the neighbouring FR-IMGT. The CDR3-IMGT is described using the IMGT unique numbering for V-DOMAIN.
Hatched circles or squares correspond to missing positions according to the IMGT unique numbering for V-REGIONs. Missing positions of the CDRs are not shown in this representation.
Arrows indicate the direction of the beta strands and their different designations in 3D structure.
For the TcR, the proteolytic cleavage site between the leader peptide and the V-REGION is putative and the assignment of amino acid 1 to one or the other region is uncertain.
