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.

textThe mature dimeric TGF-beta-1 (TGFB1) binds with high affinity to its signaling receptor, the type II receptor serine/threonine kinase (TGFBR2) (Wrana et al. 1992, Moustakas et al. 1993, Franzen et al. 1993). While type II receptor can form dimeric complexes in the absence of TGFB1 when overexpressed, it predominantly exists as a monomer on the surface of unstimulated cells under physiological conditions, and dimerization of TGFBR2 is triggered by TGFB1 binding (Zhang et al. 2009). Also, the binding of TGFBR2 with TGFB1 is further facilitated by TGFBR3, which binds primarily with TGFB2 and facilitates the TGFBR2 ligand binding (Lopez-Casillas et al. 1993). This process is inhibited by the soluble form of TGFBR3 created by MMPs. A soluble form of TGBFR3 retains its ligand binding ability and thus inhibits the binding of TGFB ligands in a competitive manner (Lopez-Casillas et al. 1994).
