Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Ligand for the T-cell-specific cell surface receptor ICOS (PubMed:10549624, PubMed:10617205, PubMed:10657606). Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; also induces B-cell proliferation and differentiation into plasma cells (PubMed:10549624, PubMed:10617205, PubMed:10657606). Could play an important role in mediating local tissue responses to inflammatory conditions, as well as in modulating the secondary immune response by co-stimulating memory T-cell function (Probable). During pregnancy, may function to skew the cytokine of maternal T-cells toward immunoprotective Th2 phenotype.SUBUNIT Interacts with CTLA4 (in vitro) (By similarity). The interaction with CTLA4 is not observed in different experimental settings (PubMed:10549624).SUBCELLULAR LOCATION Expressed in lymphoid tissues, primarily in B-cell areas (PubMed:10617205, PubMed:10657606). In the lymph nodes, strongly expressed in the cortex and in both primary and secondary follicles. In other lymphoid tissues, primarily found in the marginal zone of the spleen, the follicles in the Peyer's patches and the medulla of the thymus (PubMed:10549624, PubMed:10617205). Detected on resting splenic T-cells (at protein level) (PubMed:10549624, PubMed:10657606). Also expressed in nonlymphoid tissues, such as lung and thymus, as well as, at very low levels, in kidney, liver, peritoneum and testis (PubMed:10549624).TISSUE SPECIFICITY Expressed in brain, heart, spleen, lung, liver skeletal muscle, kidney and testis.TISSUE SPECIFICITY Expressed in heart, spleen and kidney.DEVELOPMENTAL STAGE Detected early in hemopoiesis: in the yolk sac at 11.5 and 12.5 dpc and, to a lesser extent, in the liver at 14.5 dpc.INDUCTION Up-regulated by TNF and LPS in nonlymphoid tissues.SIMILARITY Belongs to the immunoglobulin superfamily. BTN/MOG family.
