House mouse (Mus musculus) IGK locus on chromosome 6 (6C1)

The orientation of the mouse IGK locus on the chromosome is forward (FWD).

Colors are according to IMGT color menu for genes.
The boxes representing the genes are not to scale. Exons are not shown.

IGKV4-52 is not found in BAC clone AC153615. It is not yet known if IGKV4-52 represents an allele of the IGKV4-54 or a polymorphic gene by insertion deletion.

The D6Bhm9 probe (EMBL Accession number Z72363) is described in Schupp, I.W. et al., Immunogenetics, 95, 180-187 (1997).

tub: a- tubulin like (EMBL Accession number AJ235970).
sad: S-adenosyl methionine decarboxylase like (EMBL Accession number AJ132684).

The 5' enhancer (E5') is found between the IGKJ genes and the IGKC genes, and the 3' enhancer (E3') is located 8.5 kb downstream of the IGKC gene.

The 19 mouse (Mus musculus) IGKV subgroups belong to three clans (Figure IGKV clans). Clans comprise, respectively:

  • clan I: IGKV9, IGKV10, IGKV11, IGKV12, IGKV13, IGKV14, IGKV15, IGKV16 and IGKV19 subgroup genes
  • clan II: IGKV1, IGKV2, IGKV5, IGKV6, IGKV7, IGKV8 and IGKV18 subgroup genes
  • clan III: IGKV3, IGKV4 and IGKV17 subgroup genes

IMGT notes:
  1. (1) The mouse IGKV representation has been set up with data from [1-5] and updated with "The immunoglobulin k genes and the k locus of the mouse".These updates (26/05/2005) include:
    • deletion of the gaps between IGKV14-111 and IGKV2-112, and between IGKV2-116 and IGKV1-117
    • deletion of the gaps between IGKV1-122 and IGKV9-123, and between IGKV9-124 and IGKV11-125, and change of orientation and position of the IGKV9-123 and IGKV9-124 genes
    • deletion of gw1, ca9 and cc9, now considered as orphons on the same chromosome 6 (IGKV1/OR6-1, IGKV14/OR6-2 and IGKV14/OR6-3, respectively).
    These updates (17/07/2006) include:
    • Addition of IGKV8-23-1, IGKV4-57-1 and IGKV13-57-2.
    • Positioning of IGKV4-60 between IGKV4-59 and IGKV4-58.
