Bovine (Bos taurus) IGL locus on chromosome 17

The orientation of the bovine (Bos taurus) IGL locus on the chromosome 17 is forward (FWD).

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 are not included in the numbers displayed at the right ends of these two lines.

IGL gene names are according to the IMGT nomenclature [1].
The Bos taurus IGL J-C-CLUSTER comprises 9 cassettes indicated by the numbers 1 to 9 (IGLJ1-IGLC1, IGLJ2-IGLC2, IGLJ3-IGLC3, IGLJ4-IGLC4, IGLJ5-IGLC5, IGLC6, IGLJ7-IGLC7, IGLJ8-IGLC8 and IGLJ9-IGLC9, respectively).
Single arrows show genes whose polarity is opposite to that of the J-C-CLUSTER.

There are one gap at each end of the inversion. The one in 5', localized in the 3'UTR of IGLV(IV)-68*01 (complement(28197..31151)) is not represented.

RSPH14 is located at 637 kb in 3' of the IGLC9 gene, VPREB1 is located at 759 kb in 3' of the IGLC9 gene and TOP3B is located at 773 kb in 3' of the IGLC9 gene (Perrine Pégorier, 23/05/19).
