The protein encoded by this gene belongs to the thrombospondin family. Thrombospondin family members are adhesive glycoproteins that mediate cell-to-cell and cell-to-matrix interactions. This protein forms a pentameric molecule linked by a single disulfide bond. This gene shares a common promoter with metaxin 1. Alternate splicing results in coding and non-coding transcript variants.,THBS3,TSP3,Signal Transduction,Cell Biology & Developmental Biology,Cytoskeleton,Extracellular Matrix,Neuroscience,Calcium Signaling,THBS3
