Examples of C-DOMAINs: Protein displays of TR C-DOMAINs: Human and mouse TRA, TRB, TRG and TRD C-DOMAINs

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

Only the C-DOMAIN of the *01 allele of each functional or ORF 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.

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).

Protein displays of the complete C-REGIONs is available in IMGT Repertoire.

IMGT note:
(1) The first amino acid of the TRA C-REGION which results from the splicing with the J-REGION is N (codon aat), D (codon gat), Y (codon tat) or H (codon cat) for 35, 12, 7 and 4 TRAJ, respectively. See Alignment of alleles: Human TRAJ (overview) for the sequences of the 58 FUNCTIONAL and ORF TRA J-REGION.
