3D representation

IMGT 3D representations of immunoglobulin (IG), T cell receptor (TR) and major histocompatibility (MH) domains are available from the IMGT Repertoire. This visualization permits a correlation between 2D representations (IMGT Colliers de Perles) and 3D structures (IMGT/3Dstructure-DB).

Structural data are retrieved from PDB and from the literature. The IMGT unique numbering for V-DOMAIN and V-LIKE-DOMAIN [1,2], the IMGT unique numbering for C-DOMAIN and C-LIKE-DOMAIN, the IMGT unique numbering for G-DOMAIN and G-LIKE-DOMAIN and the IMGT standardization rules of the IMGT Scientific chart have been applied to sequence and 3D structure data from PDB. IMGT/3Dstructure-DB database [3] provides the first common access to annotated structural data concerning IG, TR and MH, according to IMGT-ONTOLOGY.
