Here you are: IMGT Web resources > IMGT Repertoire (IG and TR) > 2. Proteins and alleles

Only the *01 allele of each functional, ORF and in-frame pseudogenes C-REGION is shown.

Letters in red correspond to amino acids which are polymorphic in the other alleles.
For C-REGIONs, letters in bold correspond to additional positions in the IMGT unique numbering.
For C-REGIONs, letters between parentheses correspond to amino acids resulting from the splicing.

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.
- brackets, [F] and [P], when the accession number refers to genomic DNA, but not known as being germline or rearranged.

N (Asn, asparagine) of potential N-glycosylation sites (NXS/T, where X is different from P), (N-linked glycosylation) is shown is green (site is underlined in CHS and in pages edited before 14/10/2009).

The IGHC protein display numbering is according to the IMGT unique numbering for C-DOMAIN and C-LIKE-DOMAIN.
