IMGT notes:
  1. (1) In EX2 [D1] c81>t, positions according to IMGT unique numbering for V-DOMAIN and V-LIKE-DOMAIN and in EX3 [D2] c53>t, T18>M positions according to IMGT unique numbering for C-DOMAIN and C-LIKE-DOMAIN.
  2. (2) Splicing B (533 aa). No EX9. In EX2 [D1] c81>t, in EX3 [D2] c53>t; T18>M and in EX6 t50>c; L7>P and t131>c.
  3. (3) Splcing C (493 aa). EX6 utilizes an alternative 5' DONOR-SPLICE site positioned 22 nt after the original splice site.
  4. (4) Splicing D (316 aa). No EX4, 5.
  5. (5) Splicing E (316 aa). No EX3, 4.

Genomic sequence

Coding region sequence

The coding region (CODING-REGION) sequence starts from INIT-CODON (or its encoded amino acid) to STOP-CODON (not included).
The nucleotide sequence is extracted from cDNA (c) sequences and/or is built by artificial exon joining from genomic DNA (g) sequences. The amino acid sequence is the translation of the nucleotide sequence.
