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 Integrin alpha-5/beta-1 (ITGA5:ITGB1) is a receptor for fibronectin and fibrinogen. It recognizes the sequence R-G-D in its ligands. ITGA5:ITGB1 binds to PLA2G2A via a site (site 2) which is distinct from the classical ligand-binding site (site 1) and this induces integrin conformational changes and enhanced ligand binding to site 1. ITGA5:ITGB1 acts as a receptor for fibrillin-1 (FBN1) and mediates R-G-D-dependent cell adhesion to FBN1. ITGA5:ITGB1 acts as a receptor for fibronectin (FN1) and mediates R-G-D-dependent cell adhesion to FN1 (By similarity). ITGA5:ITGB1 is a receptor for IL1B and binding is essential for IL1B signaling. ITGA5:ITGB3 is a receptor for soluble CD40LG and is required for CD40/CD40LG signaling (By similarity).SUBUNIT Heterodimer of an alpha and a beta subunit. The alpha subunit is composed of a heavy and a light chain linked by a disulfide bond. Alpha-5 associates with beta-1. Interacts with NISCH. Interacts with HPS5. Interacts with RAB21 and COMP. Interacts with CIB1. ITGA5:ITGB1 interacts with CCN3. ITGA5:ITGB1 interacts with FBN1. ITGA5:ITGB1 interacts with IL1B. ITGA5:ITGB1 interacts with ACE2. ITGA5:ITGB1 interacts with SELP (By similarity). Interacts with ANGPT2. ITGA5:ITGB1 interacts with IGFBP2 (By similarity). ITGA5:ITGB1 interacts with IGFBP1 (By similarity).SUBCELLULAR LOCATION Proteolytic cleavage by PCSK5 mediates activation of the precursor.SIMILARITY Belongs to the integrin alpha chain family.
