- Fct: FUNCTIONALITY
- R: Rearranged
- T: Transcribed
- Pr: Translated into protein
"+" or "-" indicates if the gene sequences have been found (+) or not been found (-)
rearranged (R),
transcribed (T) and/or translated into protein
(Pr). Arbitrarily that information is shown on the first line of each gene
when the data have been confirmed by several studies.
Functionality is shown between parentheses, (F) and (P), when the accession
number refers to rearranged genomic DNA or cDNA and the corresponding germline
gene has not yet been isolated.
Functionality is shown between brackets, [F] and [P], when the accession number
refers to genomic DNA, but not known as being germline or rearranged.

In this table, are reported the 10 TRAV/DV genes identified so far:
- Eight TRAV/DV genes (TRAV4-4/DV10, TRAV6-7/DV9, TRAV13-4/DV7, TRAV14D-3/DV8, TRAV15D-1/DV6D-1, TRAV15-1/DV6-1, TRAV16D/DV11 and TRAV21/DV12) which have
been found rearranged to TRAJ genes and to (D)J-GENEs of the TRD locus.
- TRAV15-2/DV6-2 and TRAV15D-2/DV6D-2, which are assigned to the TRAV15 subgroup on the basis of sequence alignment, although they have not yet been found rearranged to TRAJ genes.
This does not exclude that other TRAV genes may be found rearranged to TRDD-TRDJ.
Clones used for the complete sequencing of the TRA/TRD locus (see IMGT/GeneView and Accession numbers of the Reference sequences) were later used to construct four contigs: AE008683 to AE008686.
- AE008683 (404892 bp) contains TRAV1 to TRAV7D-3.
- AE008684 (400099 bp) contains TRAV6D-4 to TRAV7-3.
- AE008685 (400099 bp) contains TRAV6-4 to TRAV12-4.
- AE008686 (461875 bp) contains TRAV13-5 to TRAV23.
The original contigs (AE008683, AE008684, AE008685 and AE008686) have been merged in EMBL into one sequence of 1666365 bp (AE007512). The four contigs has become secondary accession number of AE007512 which is annotated.
In the TRA locus of Mus musculus C57BL/6J, there is an insertion of 300 kb between TRAV15D-3 and TRAV7-2, that corresponds to a triplication of part of the TRAV genes. The triplicated genes are indicated with the letter N in their name. They comprise 34 TRAV genes (of which 27 are functional and 7 are pseudogene).
The "invariant" TR alpha chain of the murine NK1.1+ (NKR-P1C, CD161) T cells which recognize CD1d results from the TRAV11-TRAJ18 (previously Valpha14-Jalpha281)
rearrangement (it remains to be demonstrated if both the TRAV11 and TRAV11D genes, which have a 100 % identical V-REGION, are involved).
CD161 is expressed by ~ 1 % of mouse T cells and a large fraction of these CD161+ T cells are invariant NK T cells [Exley, M.A. et al.,
Current Protocols in Immunology, Wiley, J. and Sons, New York, 14, 14.11.1-14.11.13 (2002)].
