IMGT notes:
(1) Gene names (symbols) are according to the IMGT gene nomenclature (IG and TR genes), and MGI Mouse Genome Informatics or HUGO Human Genome Nomenclature Committee. Full gene designations are the following:
  • B2M: Microglobulin
  • CD1: Cluster of differentiation 1
  • CD2: Cluster of differentiation 2
  • CD3E: Cluster of differentiation 3, epsilon
  • CD4: Cluster of differentiation 4
  • CEAMCAM5: Carcinoembryonic antigen-related cell adhesion molecule 5
  • DAA: MHC class II, alpha chain
  • DAB: MHC class II, beta chain
  • DBB: MHC class II, beta chain
  • FCER1: Receptor for Fc fragment of IgE, high affinity I, Fc epsilon RI
  • FCGR1: Receptor for Fc fragment of IgG, high affinity I, Fc gamma RI (CD64)
  • FCGR2A: Receptor for Fc fragment of IgG, low affinity IIa, Fc gamma RIIa (CD32)
  • FCGR2B: Receptor for Fc fragment of IgG, low affinity IIb, Fc Gamma RIIb (CD32)
  • FCGR3B: Receptor for Fc fragment of IgG, low affinity IIIb, Fc gamma RIIIb (CD16)
  • MH2-AA: MHC class II, histocompatibility 2-A alpha, H2-IA-alpha
  • H2-AB: MHC class II, histocompatibility 2-A beta, H2-IA-beta
  • H2-K: MHC class I, histocompatibility 2-K
  • HLA-A: MHC Class I, Human leucocyte antigen -A
  • HLA-DMA: MHC class II, Human leucocyte antigen -DMA
  • HLA-DMB: MHC class II, Human leucocyte antigen -DMB
  • IGHG1: Immunoglobulin heavy constant gamma 1
  • IGHG4: Immunoglobulin heavy constant gamma 4
  • PRETA: Pre-T cell receptor
  • TRAC: T cell receptor alpha constant
  • TRBC: T cell receptor beta constant
  • TRDC: T cell receptor delta constant
  • TRGC1: T cell receptor gamma constant 1
  • UAA: MHC class I
  • UBA: MHC class I (aliases: A, B and UA)
  • UCA: MHC class I
  • UEA: MHC class I
  • UGA: MHC class I
(2) Accession numbers are from IMGT/LIGM-DB, EMBL, PDB or SWISS-PROT. Click on an accession number to get access to the database entry. For PDB, the letter added to the accession number corresponds to the chain, and sequences are from the section sequences details.
(3) Domain name or number. If no number is indicated that means that there is only one C-DOMAIN or C-LIKE-DOMAIN in the chain.
(4) G8 and GFEWCPR (positions 120-126) are according to M64239 (and replace A and D, respectively in PDB entry).
(5) A unique exon encodes domain 1 (not shown) and domain 2.
(6) B2M microglobulin (associated to HLA-B).
(7) B2M microglobulin (associated to H2-K ).
(8) IGLL2 is a Pseudogene, because of one nucleotide DELETION in EX3 (codon at positon 28 according to the IMGT numbering for C-DOMAIN and C-LIKE-DOMAIN) leading to a frameshift.
