Introduction

‘Nomenclature and overview of the mouse(Mus musculus and Mus sp.) immunoglobulinkappa (IGK) Genes’ is the 19th report of the‘IMGT Locus in Focus’ section launched inthe April 1998 issue of Experimental andClinical Immunogenetics [1–19]. This reportcomprises two figures: (1) ‘Representation ofthe mouse (Mus musculus) IGK locus onchromosome 6’ (2) ‘The classification conceptof IMGT-ONTOLOGY exemplified for themouse (Mus musculus) IGKV genes’ andeight tables entitled: (1) ‘Mouse (Mus mus-culus) germline IGKV genes and alleles’;(2) ‘Mouse (Mus musculus) IGKV orphons’;

Fig. 1. Representation of themouse (M. musculus) IGK locuson chromosome 6. Horizontal ar-rows indicate inverse orientation oftranscription of the IGKV genescompared to that of the IGKJgenes. A question mark belowIGKV4-52 and IGKV4-60 indi-cates that the orientation of tran-scription of these genes is un-known. Two enhancers have beenidentified: E5) between the IGKJgenes and the IGKC gene [28–30],and E3) located 8.5 kb downstreamof the IGKC gene [31]. The mouseIGKV representation has been setup with data from [20–24] and up-dated with ‘The immunoglobulin Îgenes and the Î locus of the mouse’(http://www.med.uni-muenchen.de/biochemie/zachau/kappa.htm) –July 2000 version. These updates,compared to the publications [20–24], include: suppression of thegaps between IGKV14-111 andIGKV2-112, and between IGKV2-116 and IGKV1-117; suppressionof the gaps between IGKV1-122and IGKV9-123, and betweenIGKV9-124 and IGKV11-125, andchange of orientation and positionof the IGKV9-123 and IGKV9-124genes; suppression of gw1, ca9and cc9, now considered as or-phons on the same chromosome 6(IGKV1/OR6-1, IGKV14/OR6-2and IGKV14/OR6-3, respective-ly). The IGKV4-52 gene is locatedbetween IGKV4-51 and IGKV4-53, but the exact distance to one orthe other gene is not known. TheD6Bhm9 probe (EMBL Acces-sion number Z72363) is describedin Schupp IW, et al: Immuno-genetics 1997;95:180–187. Tub =a-tubulin like (EMBL AccessionNo. AJ235970). Sad = S-adeno-syl methionine decarboxylase like(EMBL Accession No. AJ132684).

The mouse (M. musculus) IGK locus,located on chromosome 6, spans 3,200 kb.It consists of 158 IGKV genes [20–24],belonging to 19 subgroups, localized on3,100 kb, 5 IGKJ genes [25–26] and 1 IGKCgene [27]. The potential genomic M. musculusIGK repertoire comprises 93 functionalIGKV genes belonging to 18 subgroups, 5IGKJ and 1 IGKC gene. The total number ofmouse (M. musculus) IGK genes per haploidgenome is 164 (174 if the orphons are in-cluded), of which 99 are functional. Eighty-one IGKV genes are in opposite orientation oftranscription, 59 of them are functional andmust rearrange by a mechanism of inversion.IMGT gene names and definitions of themouse (M. musculus) IGK genes on chro-mosome 6 and IGK orphons are providedwith the gene functionality and the numberof alleles, according to the concepts of IMGT-ONTOLOGY [32] and to rules of the IMGTScientific chart, with the accession numbersof the IMGT reference sequences. These ta-bles and figures are available at the IMGTMarie-Paule page of IMGT, the internation-al ImMunoGeneTics database (http://imgt.cines.fr) created by Marie-Paule Lefranc,Université Montpellier II, CNRS, France[33–35]. Description of functionality (FUNC-TIONAL, ORF, PSEUDOGENE) and de-scription of mutations are according to theIMGT scientific chart available at the IMGTMarie-Paule page.

IGK Gene Nomenclature and IMGTScientific Chart

Gene NamesGene names (tables 1, 2, 5, 7, 8) are accord-

ing to the IMGT gene name nomenclaturefor IG and TR of all vertebrates based onthe ‘CLASSIFICATION’ concept of IMGT-ONTOLOGY [32] (Appendix), and accordingto rules of the IMGT Scientific chart [1] avail-able at http://imgt.cines.fr.

FunctionalityCriteria of functionality (F: functional, P:

pseudogene, ORF: open reading frame) (tables1, 2, 5–8) are described in the IMGT Scientificchart [1]. The definition of functionality isbased on sequence analysis. As examples, theinstances functional (for germline V, D, J, andfor C genes) mean that the coding regions havean open reading frame without a stop codon,and that there is no described defect in thesplicing sites, and/or recombination signals,and/or regulatory elements. According to thegravity of the identified defects, the functional-ity can be defined as ORF, pseudogene or ves-tigial (for germline V, D, J, and for C genes) [1].Complete definitions are available in theIMGT Scientific chart at the IMGT Marie-Paule page. Information on gene rearrange-ment, DNA transcription into mRNA, andRNA translation into a polypeptide chain isprovided in the IMGT ‘Germline gene tables’in the IMGT Repertoire (columns designatedas R, T, and Pr, respectively). This informationis extracted from the literature and throughIMGT/LIGM-DB sequence database search[33–35]. The IMGT/V-QUEST tool, availableat the IMGT Home page at http://imgt.cines.fr,allows the identification of the germline IGKVand IGKJ genes from IGKV-J genomic rear-rangements and transcripts, and providestranslation and 2D representation (Collier dePerles) of the variable regions [33–36].

Reference SequencesFor each gene, an IMGT reference se-

quence accession number is given (tables 1, 2,5–8). For the functional or ORF genes, theIMGT reference sequence accession numberis that corresponding to the allele *01. Notethat the number *01 does not necessarilymean that other alleles are already known, butit signifies that any new polymorphic se-quence will be described by comparison tothat allele *01. Although the IMGT accessionnumbers are the same as those from theEMBL/GenBank/DDBJ generalist databases,the content of the IMGT/LIGM-DB flat files

differs by the expertized annotations, addedby IMGT.

AllelesThe number of alleles of the IGKV, IGKJ

and IGKC genes (tables 1, 6–8) is accordingto ‘Tables of alleles and Alignments of alleles,in the IMGT Repertoire. Alignments of allknown germline functional and ORF se-quences assigned to the different alleles, bycomparison to the allele *01, are displayed athttp://imgt.cines.fr. A dash (–) indicates thatallele polymorphism of the pseudogenes hasnot been studied.

Correspondences betweenNomenclatures and Numberings

Correspondence between the mouse IGKVgroup and gene nomenclatures is reported intable 3.

In order to easily compare sequences ofimmunoglobulins and T cell receptors, aunique numbering has been defined for thevariable regions [36, 37]. Correspondence be-tween the IMGT unique numbering and othernumberings for the IGKV genes is availablefrom the IMGT Scientific chart. The IMGTunique numbering relies on the high conser-vation of the structure of the variable region.This numbering takes into account and com-bines the definition of the framework (FR)and complementarity determining regions(CDR) [38], structural data from X-ray dif-fraction studies [39], and the characterizationof the hypervariable loops [40]. The uniquenumbering has allowed the redefinition of thelimits of the FR and CDR [36]. The FR-IMGT and CDR-IMGT lengths themselves

become crucial information characterizingthe variable regions belonging to a group, asubgroup, and/or a gene. For example, for agermline gene of the mouse (M. musculus)IGKV1 subgroup, the lengths of the 3 CDR-IMGT, in number of amino acids is designat-ed as [11.3.7] (IMGT Repertoire12D and 3Dstructures) [36]. The unique numbering isused as the output of the IMGT/V-QUESTalignment tool, and in the ‘Alignments ofalleles (IMGT Repertoire1Proteins and al-leles).

Appendix

The ‘CLASSIFICATION’ concept ofIMGT-ONTOLOGYThe ‘CLASSIFICATION’ concept of IMGT-ON-

TOLOGY (fig. 2) organizes the immunogeneticsknowledge useful to name and classify the immuno-globulin genes [32].

‘Locus’: A locus is a group of immunoglobulingenes that are ordered and are localized in the samechromosomal location in a given species. The ‘locus’IGK on chromosome 6 is one of the three main immu-noglobulin loci in the mouse genome. Immunoglobulingenes have also been identified in other chromosomallocations outside the main loci which represent newinstances of the concept locus. However, the genes theycontain, designated as orphons, are not functional.

‘Group’: A group is a set of genes which share thesame ‘gene type’ (V, D, J or C) and participate poten-tially in the synthesis of a polypeptide of the same‘chain type’. By extension, a group includes the relatedpseudogenes and orphons. A 4-letter root designatesthe ‘group’: for example, IGKV, IGKJ, and IGKC forthe immunoglobulin kappa genes.

‘Subgroup’: A subgroup is a set of genes whichbelong to the same group, in a given species, and whichshare at least 75% identity at the nucleotide level (in

the germline configuration for V, D, and J). For exam-ple, the mouse (M. musculus) IGKV genes belong to 19subgroups.

‘Gene’: A gene is defined as a DNA sequence thatcan be potentially transcribed and/or translated (thisdefinition includes the regulatory elements in 5) and 3),and the introns, if present). Instances of the ‘gene’ con-cept are gene names. By extension, orphons and pseu-dogenes are also instances of the ‘gene’ concept. Foreach gene, IMGT has defined a reference sequence.For the V, D, and J genes, the reference sequence cor-responds to a germline entity. The rules for the choiceof the reference sequences are described at http://imgt.cines.fr in the IMGT Scientific chart.

‘Allele’: An allele is a polymorphic variant of agene. Alleles are described, exhaustively and in a stan-dardized way, for the four ‘core’ coding regions, that isthe germline V-REGIONs, D-REGIONs, and J-RE-GIONs, and for the C-REGIONs, from immunoglobu-lin genes. These alleles refer to sequence polymor-phisms, with mutations described at the sequence level[1]. Their sequences are compared to the referencesequence designated as *01 (see IMGT Scientific chartat http://imgt.cines.fr for IMGT description of muta-tions, and IMGT allele nomenclature for sequencepolymorphisms).
