In cattle (bovine, Bos taurus) and sheep (ovine, Ovis aries), the TRG genes are organized in two separate loci on chromosome 4:
Legend:
Colors are according to IMGT color menu for genes.
The boxes representing the genes are not to scale. Exons are not shown.
A double slash // indicates a gap in genome assembly. Distances in bp (base pair) or in kb (kilobase) associated with a double slash are taken
into account in the length of the lines and included in the numbers displayed at the right end of the lines.
A dotted line ... indicates the distance in kb (kilobase) between the locus and its bornes (5' borne and the most 5' gene in the locus and/or 3'
borne and the most 3' gene in the locus) on the top and bottom lines, respectively. These distances are not represented at scale and/or are not
included in IMGT-LOCUS-UNIT and may not be included in the numbers displayed at the right ends of these two lines
.
Arrows indicate the TRGC cassettes and the transcriptional orientation of their genes.
* In AY644518 TRGV5-2 is rearranged with TRGJ2-1 and TRGV6-2 is rearranged with TRGJ6-1.
* When needed, indicate the presence of allele(s) with another functionality: see above Bovine (Bos taurus) TRG locus on chromosome 4 (4q3.1 and 4q1.5-2.2)
