Summary

Expression: HEK293
Functional: Yes (ELISA)
Amino Acid Range: Ser18-Gly287

SKU: 4286parent Categories: proteins, Recombinant proteins Tag: active proteins

Weight	1 lbs
Dimensions	9 × 5 × 2 in
accession	O95727
express system	HEK293
product tag	C-His
purity	> 95% as determined by Tris-Bis PAGE
background	Class-I Restricted T Cell-Associated Molecule (CRTAM) is a protein that is expressed after T cell activation. The interaction of CRTAM with its ligand, nectin-like 2 (Necl2), is required for the efficient production of IL-17, IL-22, and IFNγ by murine CD4 T cells, and it plays a role in optimal CD8 T and NK cell cytotoxicity. CRTAM promotes the pro-inflammatory cytokine profile; therefore, it may take part in the immunopathology of autoimmune diseases such as diabetes type 1 or colitis.
molecular weight	The protein has a predicted MW of 31.1 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1EU per μg by the LAL method.

Gene names CRTAM,CRTAM
Protein family Nectin family
Mass 9606Da
Function Mediates heterophilic cell-cell adhesion which regulates the activation, differentiation and tissue retention of various T-cell subsets (By similarity). Interaction with CADM1 promotes natural killer (NK) cell cytotoxicity and IFNG/interferon-gamma secretion by CD8+ T-cells in vitro as well as NK cell-mediated rejection of tumors expressing CADM1 in vivo (PubMed:15811952). Regulates CD8+ T-cell proliferation in response to T-cell receptor (TCR) activation (By similarity). Appears to be dispensable for CD8+ T-cell-mediated cytotoxicity (By similarity). Interaction with SCRIB promotes the late phase of cellular polarization of a subset of CD4+ T-cells, which in turn regulates TCR-mediated proliferation and IFNG, IL17 and IL22 production (By similarity). By interacting with CADM1 on CD8+ dendritic cells, regulates the retention of activated CD8+ T-cells within the draining lymph node (By similarity). Required for the intestinal retention of intraepithelial CD4+ CD8+ T-cells and, to a lesser extent, intraepithelial and lamina propria CD8+ T-cells and CD4+ T-cells (By similarity). Interaction with CADM1 promotes the adhesion to gut-associated CD103+ dendritic cells, which may facilitate the expression of gut-homing and adhesion molecules on T-cells and the conversion of CD4+ T-cells into CD4+ CD8+ T-cells (By similarity).
Catalytic activity #N/A
Subellular location Cell membrane ; Single-pass type I membrane protein. Note=In a subset of CD4+ T-cells, colocalizes with SCRIB at the immunological synapse during the late phase of T-cell activation.
Tissues In the immune system, expression is restricted to activated class-I MHC-restricted cells, including NKT and CD8 T-cells (PubMed:10811014, PubMed:15811952, PubMed:16300832). Strongly expressed in spleen, thymus, small intestine, peripheral blood leukocyte, and in Purkinje neurons in cerebellum. Expressed at much lower levels in testis, ovary, colon, lung and lymphoid tissues (PubMed:16300832).
Structure Monomer (PubMed:23583034). May form homodimer (via Ig-like V-type domain) (PubMed:23583034, PubMed:23871486). Interacts (via Ig-like V-type domain) with CADM1 (via Ig-like V-type domain); the interaction competes with CRTAM homodimerization and CADM1 homodimerization (PubMed:15781451, PubMed:15811952, PubMed:23871486). Interacts (via PDZ-binding motif) with SCRIB (via PDZ domain 3); the interaction promotes CRTAM and SCRIB polarization in a subset of CD4+ T-cells (By similarity).
