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 Involved in T-cell adhesion processes. Plays a role in a late step of leukocyte extravasation helping leukocytes to overcome the endothelial basement membrane. Acts at the same site as, but independently of, PECAM1.SUBUNIT Homodimer. Interacts with PILRB.SUBCELLULAR LOCATION Widely expressed with high levels in lung, spleen, thymus, liver and spinal cord. Expressed on leukocytes and endothelial cell contacts. Detected in a wide range of T-cells, including CD4-/CD8- and CD4+/CD8+ thymocytes. Expression is much lower in peripheral T-cells than in thymocytes.SIMILARITY Belongs to the CD99 family.
