When several alleles are shown, the nucleotide mutations and amino acid changes for a given codon are indicated
in red letters.
Dashes indicate identical nucleotides. Dots indicate gaps by comparison to the longest
sequence. Blanks indicate partial sequences (blanks at the 5' and/or 3' end).
The nucleotide between parentheses at the beginning of exons comes from a DONOR-SPLICE (n from ngt). The first nucleotide from an INT-DONOR-SPLICE is underlined (n from ngt).
Exon names are shown between parentheses on the first line.
The Cysteines involved in the IG CH1, CH2 and CH3 intrachain disulfide bridge are shown with a larger letter C in purple.
The Cysteines involved in the H-L or H-H interchain disulfide bridge are shown with a larger letter C in black.
STOP-CODON is indicated by an asterisk.
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).
