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.

textThrombospondin-1 (THBS1) is a trimeric protein held together by interchain disulphide bonds at Cys-252 and Cys-256 (Sottile et al. 1991). It was originally identified as a platelet alpha granule protein (Lawler et al. 1978) and subsequently found to be produced and secreted by a number of cell types such as endothelial cells, fibroblasts, adipocytes, smooth muscle cells, monocytes, macrophages, and transformed cells such as malignant glioma cells. Proposed functions include an involvement in platelet aggregation, cell adhesion, cell growth, angiogenesis, binding and activation of latent transforming growth factor-b and regulation of protease activities (Chen et al. 1996, Lopez-Dee et al. 2011). Several TSP-1 receptors have been identified, including CD36 (Asch et al. 1987) and several integrins including alphavbeta3 (Sun et al. 1992), alpha3beta1 (DeFreitas et al. 1995), alpha4beta1, alpha5beta1 (Yabowitz et al. 1993), and either alpha2bbeta3 or alpha2beta1 (Tuszynski & Kowalska 1991). Integrins alpha4beta1 and alpha6beta1 binds THBS1 and the related trimeric THBS2 (Anilkumar et al. 2002, Calzada et al. 2003, 2004).
