简单介绍：
Human B7-H1/PD-L1/CD274 protein (Recombinant) (C-hFc&His) (STJP000958)
详情介绍：
Host: HEK293 cells
Reactivity: Human
Note: STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS.
Short Description: Recombinant-Human B7-H1/PD-L1/CD274-C-hFc&His protein was developed from hek293 cells and has a target region of C-hFc&His. For use in research applications.
Formulation: Lyophilized from a 0.22 Mu m filtered solution of PBS, pH 7.4. Contact us for customized product form or formulation.
Immunoreactivity: Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human PD-1 at 5 Mu g/mL (100 Mu L/well) can bind Recombinant Human PD-L1 with a linear range of 0.5-2.2 Mu g/mL.
Gene Symbol: CD274
Gene ID: 29126
Uniprot ID: PD1L1_HUMAN
Immunogen: Recombinant Human B7-H1/PD-L1/CD274 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Phe19-Thr239) of human PD-L1/B7-H1 (Accession #NP_054862.1) fused with an Fc, 6×His tag at the C-terminus.
Tissue Specificity Highly expressed in the heart, skeletal muscle, placenta and lung. Weakly expressed in the thymus, spleen, kidney and liver. Expressed on activated T- and B-cells, dendritic cells, keratinocytes and monocytes. Isoform 4: Widely expressed, highest in lung, liver and pituitary and in various peripheral blood cells, including neutrophils and some subtypes of lymphoid and myeloid cells.
Post Translational Modifications Ubiquitinated.STUB1 likely mediates polyubiquitination of PD-L1/CD274 triggering its degradation. Ubiquitinated by MARCHF8.leading to degradation.
Function Plays a critical role in induction and maintenance of immune tolerance to self. As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response. Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10). Can also act as a transcription coactivator: in response to hypoxia, translocates into the nucleus via its interaction with phosphorylated STAT3 and promotes transcription of GSDMC, leading to pyroptosis. The PDCD1-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and escape destruction by the immune system, thereby facilitating tumor survival. The interaction with PDCD1/PD-1 inhibits cytotoxic T lymphocytes (CTLs) effector function. The blockage of the PDCD1-mediated pathway results in the reversal of the exhausted T-cell phenotype and the normalization of the anti-tumor response, providing a rationale for cancer immunotherapy.
