Proteins with known 3D structures
Overview: Human Immunoglobulins
Overview table  Identification of the genes and alleles involved in the rearrangements and expressed in the variable regions Protein display of the Ig V-D-J and V-J REGIONs

"OVERVIEW" gives information on proteins whose three-dimensional structure has been determined.
"IDENTIFICATION AND COLLIERS DE PERLES" provides
  • the identification of the genes and alleles expressed in the IGH V-DOMAINs (V-D-J-REGIONs) and in the IGK and IGL V-DOMAINs (V-J-REGIONs)
  • the Colliers de Perles of the IGH, IGK and IGL V-DOMAINs.
    "PROTEIN DISPLAY" provides the Protein displays of the IGH, IGK and IGL V-DOMAINs.
