4-1BBL/TNFSF9 Protein, Mouse (HEK293, His)

Customer Review

Based on 1 Customer Validation

4-1BBL (4-1BB ligand) is a type II membrane protein of the TNF superfamily, is expressed on antigen-presenting cells. 4-1BB with 4-1BBL can induce T-cell expansion, cytokine induction, differentiation, and upregulation of anti-apoptotic genes as well as protect T cells from activation-induced cell death (AICD). 4-1BBL stimulates T cell proliferation and induces effective anti-tumor immune responses. 4-1BBL is an immunostimulant molecule that interacts with the 4-1BB high-affinity receptor during the antigen presentation, providing costimulatory signals to both CD4+ and CD8+ T cells through the activation of NF-kB, c-Jun, and p38 downstream pathways, triggering pleiotropic effects on the immune system. 4-1BBL/TNFSF9 Protein, Mouse (HEK293, His) is a recombinant protein with a N-Terminal His label, It consists of 206 amino acids (R104-E309) and is produced in HEK293 cells.

Biological Activity

Description

4-1BBL (4-1BB ligand) is a type II membrane protein of the TNF superfamily, is expressed on antigen-presenting cells. 4-1BB with 4-1BBL can induce T-cell expansion, cytokine induction, differentiation, and upregulation of anti-apoptotic genes as well as protect T cells from activation-induced cell death (AICD)[1]. 4-1BBL stimulates T cell proliferation and induces effective anti-tumor immune responses[3]. 4-1BBL is an immunostimulant molecule that interacts with the 4-1BB high-affinity receptor during the antigen presentation, providing costimulatory signals to both CD4+ and CD8+ T cells through the activation of NF-kB, c-Jun, and p38 downstream pathways, triggering pleiotropic effects on the immune system[4]. 4-1BBL/TNFSF9 Protein, Mouse (HEK293, His) is a recombinant protein with a N-Terminal His label, It consists of 206 amino acids (R104-E309) and is produced in HEK293 cells.

Background

4-1BBL is expressed on a variety of antigen presenting cells (APCs), including activated B cells, dendritic cells, macrophages, and myeloid cells[1].
The amino acid sequence of human 4-1BBL protein has low homology for mouse and rat 4-1BBL protein.
4-1BBL binds to high-affinity 4-1BB, resulting in the recruitment of intracellular TRAF adaptor molecules (TRAF1 and TRAF2), and then activate of NF-jB and the extracellular signal regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and p38 mitogen-associated protein (MAP) kinase signaling cascades. The binding of 4-1BBL to 4-1BB generates strong co-stimulatory signals in T-cells that lead to up-regulation of anti-apoptotic molecules, cytokine secretion, and enhanced effector function[2].
4-1BBL is a member of the TNF family of proteins. 4-1BBL is an immunostimulant molecule that interacts with the 4-1BB high-affinity receptor during the antigen presentation, providing costimulatory signals to both CD4+ and CD8+ T cells through the activation of NF-kB, c-Jun, and p38 downstream pathways, triggering pleiotropic effects on the immune system[4]. 4-1BBL significantly induces T cell proliferation and increases the stimulation of both IL-2 and IFN-γ[5].

In Vitro

4-1BB (hamster ovary; 5 μg/mL; 16 h) costimulates B lymphocyte proliferation[4].
