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.

Teleostei light chain type is Ig-Light-Iota (IGI).

The Channel catfish (Ictalurus punctatus) IGIV genes and alleles have a temporary designation based on the IMGT gene name nomenclature rules for the unmapped genes, the incomplete loci, or the cDNAs in the absence of germline genes.

IMGT notes:
  1. (1) Partial V-REGION: AA 1 to 40 are missing (no FR1-IMGT, no CDR1-IMGT and partial FR2-IMGT).
  2. (2) Partial V-REGION: AA 1 to 11 are missing (partial FR1-IMGT).
  3. (3) In frame STOP-CODON at codon 86 in the FR3-IMGT (positions 256-258 in IMGT unique numbering).
  4. (4) Pseudogene because frameshift in CDR1-IMGT.
  5. (5) Partial V-REGION in 3'
