Here you are: IMGT Web resources > IMGT Repertoire (IG and TR) > 1. Locus and genes

"+" 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.

IMGT notes:
  1. (1) This sequence has been artificially constructed by junction of the sequences from 19 overlapping clones.
  2. (2) The one nucleotide difference most probably derive from hypersomatic mutation [11], as this IGHJ2 germline segment is downstream of a IGH V-D-J1 rearrangement. This accession number is therefore not included in Table of alleles and Alignments of alleles.
  3. (3) Partial J-REGION: two nucleotides missing in 5'.
  4. (4) Pseudogene due to a STOP-CODON.
  5. (5) The two nucleotide differences most probably derive from hypersomatic mutations [11], as this IGHJ3 germline segment is downstream of a IGH V-D-J1 rearrangement. This accession number is therefore not included in Table of alleles and Alignments of alleles.
  6. (6) Mus sp. species sequence.
