The human TRB locus is located on the long arm of chromosome 7 at 7q34, at 154 Mb from the 7pter telomere and at about 19 Mb from the 7qter telomere.
The human TRB locus is in forward orientation: being located on the chromosome long arm, the 5' end of the locus is centromeric and the 3' end is telomeric.
In IMGT/GeneSearch, IMGT/GeneView and IMGT/LocusView:
The TRB locus localization (start and end: 91557-667340 bp) and the gene positions are those in the L36092 accession number.
The original L36092 sequence (684973 bp) has been split in
EMBL into three sequences of 267156 bp (U66059), 215422 bp (U66060) and
232650 bp (U66061), L36092 has become secondary accession number of
U66059, U66060 and U66061. In IMGT, the original sequence
L36092 which is fully annotated has also been kept as primary
accession number, in addition to U66059, U66060 and U66061.
Clones (in blue) are those used for the complete sequencing of the human TRB locus.
