The IGHC protein display numbering is according to the IMGT unique numbering for C-DOMAIN and C-LIKE-DOMAIN.
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).
The hinge exon(s) are shown at the end of the protein display.
