Description / human CD27 ligand, soluble protein (His-Tag)
CD27 Ligand, a type II transmembrane protein, is a member of the TNF superfamily. It is expressed on activated T and B lymphocytes as well as NK cells. CD27 Ligand and its receptor (CD27) regulate the immune response by promoting T-cell expansion and differentiation, as well as NK enhancement. CD27 signalling can act as a costimulatory effector to sustain the survival of CD8+ T cells, primarily by inducing increased expression of the IL-2 gene. Full length human CD27 Ligand is a 193 amino acid protein, consisting of a 17 amino acid cytoplasmic domain, a 21 amino acid transmembrane domain, and a 155 amino acid extracellular domain. Recombinant Human Soluble CD27 Ligand corresponds to the 155 amino acid extracellular domain of the full length CD27 Ligand protein plus an N-terminal His-Tag and has a calculated molecular weight of approximately 18.8 kDa.
