DESCRIPTION

Also known as TSP1_HUMAN, THBS1, TSP, TSP1. Adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. Binds heparin. May play a role in dentinogenesis and/or maintenance of dentin and dental pulp (By similarity). Ligand for CD36 mediating antiangiogenic properties. Plays a role in ER stress response, via its interaction with the activating transcription factor 6 alpha (ATF6) which produces adaptive ER stress response factors (By similarity). Homotrimer; disulfide-linked. Interacts (via the TSP type I repeats) with HRG; the interaction blocks the antiangiogenic effect of THBS1 with CD36 (By similarity). Can bind to fibrinogen, fibronectin, laminin, type V collagen and integrins alpha-V/beta-1, alpha-V/beta-3 and alpha-IIb/beta-3. Interacts (via the TSP type I repeats) with CD36; the interaction conveys an antiangiogenic effect. Interacts with ATF6 (via lumenal domain) (By similarity).
