Background

Function：Plays a critical role in induction and maintenance of immune tolerance to self (PubMed:11015443, PubMed:28813410, PubMed:28813417, PubMed:31399419). As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response (PubMed:11015443, PubMed:28813410, PubMed:28813417, PubMed:36727298). Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10) (PubMed:10581077). 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 (PubMed:32929201)|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 (PubMed:28813410, PubMed:28813417). The interaction with PDCD1/PD-1 inhibits cytotoxic T lymphocytes (CTLs) effector function (By similarity). 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 (By similarity)

Subcellular Localization：Cell membrane,Early endosome membrane,Recycling endosome membrane,Nucleus,Cell membrane,Endomembrane system,Secreted

Expression：
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|Widely expressed, highest in lung, liver and pituitary and in various peripheral blood cells, including neutrophils and some subtypes of lymphoid and myeloid cells
Induction: Up-regulated on T- and B-cells, dendritic cells, keratinocytes and monocytes after LPS and IFNG activation. Up-regulated in B-cells activated by surface Ig cross-linking

Isoforms & Post-Translational Modification：Q9NZQ7 has four isomers: Q9NZQ7-1: 33275 Da (predicted); Q9NZQ7-2: 20246 Da (predicted); Q9NZQ7-3: 20454 Da (predicted); Q9NZQ7-4: 28050 Da (predicted).
Ubiquitinated; STUB1 likely mediates polyubiquitination of PD-L1/CD274 triggering its degradation (PubMed:28813410)

Subunit：Interacts with PDCD1 (PubMed:11015443, PubMed:18287011, PubMed:26602187)
