IMGT notes:
  1. (1) Three alternative spliced transcripts are mentioned in PUBMED:7499829. Splicing A (356 aa) has exons EX1,2 and EX6-11. Splicing C (314 aa) has exons EX5 and EX7-11. Splicing B (309 aa) has exons EX4 and EX7-11. No cDNA is available for splicing C.
  2. (2) Splicing B. In EX8 [D2] a79>g; K26>R, positions according to IMGT unique numbering for C-DOMAIN and C-LIKE-DOMAIN.
  3. (3) Splicing B. In EX8 [D2] a288.4>g; K96.4>R, positions according to IMGT unique numbering for C-DOMAIN and C-LIKE-DOMAIN.
  4. (4) Splicing B. Five nucleotide variations in EX7 [D1], EX8 [D2] and EX9.

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.
