Human CRTAM Protein, His Tag

Source : 

Human CRTAM, His Tag (CRM-H52H3) is expressed from human 293 cells (HEK293). It contains AA Ser 18 - Gly 287 (Accession # O95727-1).

 

Molecule : CRTAM

 

Synonyms : CRTAM,CD355

 

Format : Powder

 

Category : Other Recombinant Proteins

 

Accession : NP_062550.2

 

Storage : -20℃

 

Shipping condition : Powder,RT

 

Molecular Weight : 31.9 kDa

 

Characteristics :

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 31.9 kDa. The protein migrates as 45-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

 

Endotoxin Level : Less than 1.0 EU per μg by the LAL method.

 

Buffer : PBS, pH7.4

 

Description :

Class I-restricted T cell-associated molecule (CRTAM), a member of nectin family and the immunoglobulin superfamily, is also known as cytotoxic and regulatory T-cell molecule, which is expressed by activated CD8+ and NK T cells. CRTAM is found in spleen, thymus, small intestine, peripheral blood, and surprisingly, in brain where it is highly expressed by Purkinje cells of the cerebellum. The high affinity of CRTAM/IGSF4 adhesion allows CRTAM to disrupt IGSF4 homotypic interactions (3 - 5). IGSF4 and T cell receptor co-engagement of CRTAM-expressing CD8+ cells induces increased IFN-gamma or IL-22 production (3, 4). Furthermore, a role in cancer surveillance through NK cell-mediated rejection of IGSF4-expressing tumors has been proposed.
