"+" or "-" indicates if the gene sequences have been found (+) or not been found (-) rearranged (R), transcribed (T) and/or translated into protein (Pr). Arbitrarily that information is shown on the first line of each gene when the data have been confirmed by several studies.

Functionality is shown between parentheses, (F) and (P), when the accession number refers to rearranged genomic DNA or cDNA and the corresponding germline gene has not yet been isolated.
Functionality is shown between brackets, [F] and [P], when the accession number refers to genomic DNA, but not known as being germline or rearranged.

MAP: Mapped reference sequences.

IMGT notes:
  1. (1) Non canonical J-REGION: Phe-Ser-X-Asn instead of Phe-Gly-X-Gly, and non canonical J-HEPTAMER: CGTTGCC instead of CACAGTG.
  2. (2) DELETION of two nucleotides in J-HEPTAMER: CAGTG instead of CACAGTG.
  3. (3) Note that the sequences of Mus musculus IGLJ4*01 and Mus spretus IGLJ4*01 are identical.
  4. (4) X58411 contains the IGLJ1, IGLC1, IGLJ3 and IGLC3 genes from the BALB/c MOPC 315 B cell line. Originally these genes were submitted independently (X58411 being the IGLC1 accession number). Secondary accession numbers of X58411 correspond to the primary accession numbers of IGLJ1 (X58419/M28320), IGLJ3 (X58421/M28322/M28323) and IGLC3 (X58415/M28327) from MOPC 315.
  5. (5) X58414 contains the IGLJ2, IGLC2, IGLJ4 and IGLC4 genes from the BALB/c MOPC 315 B cell line. Originally these genes were submitted independently (X58414 being the IGLC2 accession number). Secondary accession numbers of X58414 correspond to the primary accession numbers of IGLJ2 (X58420/M28321), IGLJ4 (X58422/M28324) and IGLC4 (X58416) from MOPC 315. The secondary accession number X58410/M28329 corresponds to the primary accession number of IGLC4 from BALB/c J 558 cell line, whose sequence is identical to that of MOPC 315.
