Name :
Human CD70/CD27L/CD27LG/TNFSF7 Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant
Description :
CD70, also known as CD27L (CD27 Ligand), is a member of the tumor necrosis factor superfamily (TNFSF7). CD70 is a single-pass type II transmebrane glycoprotein consisting of a short cytoplasmic domain (1-17aa), a transmembrane domain (TM: 18-38 aa) and a 155aa extracellular domain (ECD: 39-193 aa). CD70 exists as a trimer that is found on activated T-and B-lymphocytes and mature dendritic cells. The expression of CD70 is induced by antigen receptor activation in B cells and at low levels in mouse T cells. CD70 interacts with CD27, a member of the TNF receptor superfamily (TNFRSF7) that is expressed on natural killer (NK) cells and subsets of T and B cells. Ligation with CD27 on T cells provides co-stimulatory signals for T cell proliferation, clonal expansion and the promotion of effector T cell function. On NK cells, ligation of CD70 induces proliferation and IFN-gamma production. CD70 expression on tumor cells coupled with its highly restricted expression on normal tissues makes CD70 an attractive target for immunotherapy.
