Protein display: Bovine (Bos taurus) IGH C-REGIONs

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.

IMGT notes:
(1) IGHG1*03 (cDNA) has a polymorphic amino acid INSERTION between codon 99 and 100 in the IMGT unique numbering for C-DOMAIN
(2) IGHG2*02 (cDNA) has a polymorphic amino acid INSERTION between codon 99 and 100 in the IMGT unique numbering for C-DOMAIN
(3) Twenty-two additional amino acids are encoded by the 3' end of CH1. As this region is rich in proline (7 aa out of 22), it is likely to be part of the structural hinge [1].
