Product Background

Gene summary
CRTAM (Cytotoxic And Regulatory T-Cell Molecule) is a Protein Coding gene. Among its related pathways are Immune System and Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell. GO annotations related to this gene include receptor binding. An important paralog of this gene is CADM3. The CRTAM gene is upregulated in CD4 (see MIM 186940)-positive and CD8 (see CD8A; MIM 186910)-positive T cells and encodes a type I transmembrane protein with V and C1-like Ig domains (Yeh et al. , 2008 [PubMed 18329370]).
Antigen Description
Class-I MHC-restricted T-cell associated molecule (CRTAM), designated as CD355, is an Ig domain like type I transmembrane receptor, which belongs to the nectin family. In the immune system, CRTAM is strictly expressed on activated NK cells and activated CInteraction with CADM1 promotes natural killer (NK) cell cytotoxicity and interferon-gamma (IFN-gamma) secretion by CD8+ cells in vitro as well as NK cell-mediated rejection of tumors expressing CADM3 in vivo. The function about CRTAM antigen include protein binding; receptor binding; receptor binding; receptor binding.
