Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000536
UniProt IDP19256
Primary gene name(s)CD58
Synonym gene name(s)LFA3
Protein nameLymphocyte function-associated antigen 3
Protein functionLigand of the T-lymphocyte CD2 glycoprotein. This interaction is important in mediating thymocyte interactions with thymic epithelial cells, antigen-independent and -dependent interactions of T-lymphocytes with target cells and antigen-presenting cells and the T-lymphocyte rosetting with erythrocytes. In addition, the LFA-3/CD2 interaction may prime response by both the CD2+ and LFA-3+ cells.
Subcellular locationIsoform 1: Cell membrane;
Single-pass type I membrane protein.;
SUBCELLULAR LOCATION: Isoform 2: Cell membrane;
Lipid-anchor, GPI-anchor.
