PD-L1 (CD274/B7-H1) is a critical membrane-bound costimulatory molecule belonging to the B7 superfamily that inhibits immune responses through its receptor, PD-1. PD-L1 plays a key role in the pathogenesis of inflammatory diseases (programmed death 1). It is widely expressed in the mononuclear phagocyte system (MPS), may co-stimulate T cells, and regulates inflammatory responses. PD-L1 exerts inflammation regulatory functions via a negative co-stimulatory effect on T cell functions to inhibit cytokine secretion, facilitate apoptosis of activated T cells and induce T cell anergy. Aberrant expression and dysregulation of CD274/PD-L1 have been reported during bacterial infection, inflammation, and in numerous autoimmune diseases.

Western blot analysis: 2-4 µg/ml; Immunohistochemical analysis-5-10 µg/ml; FACS: 1-2 µg/ml

For Research Use Only. Not for use in diagnostic/therapeutics procedures.

Subcellular location:	Endomembrane system
Post transnational modification:	Ubiquitinated; STUB1 likely mediates polyubiquitination of PD-L1/CD274 triggering its degradation.
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.
