LAG3

lymphocyte-activation gene 3

Lymphocyte-Activation Protein 3 (LAG3) belongs to Ig superfamily and contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. The sequence data, exon/intron organization, and chromosomal localization all indicate a close relationship of LAG3 to CD4.

Gene Name: lymphocyte-activation gene 3
Synonyms: LAG3, CD223 antigen, LAG-3, Protein FDC, CD223, FDC, Lymphocyte-activation gene 3
Target Sequences: NM_002286 P18627 P18627
