Human CD90/THY1 Protein, ECD (Extracellular Domain), Fc-fusion, Recombinant
CD90, also known as Thy1, is a GPI-anchored cell membrane protein that contains one immunoglobulin (Ig)-like V-type (IgV) domain in the extracellular region. Cd90 is thus a member of the Ig superfamily that mediates cellular adhesion and exerts a wide range effects in different tissues. CD90 was originally identified on mouse thymocytes as a thymocyte and pan T cell marker in mouse but not in human. CD90 is also found on various stem cells and non-lymphoid tissues such as on fibroblasts, brain cells, and activated endothelial cells. It is expressed on hematopoietic progenitor cells, neurons, and activated vascular endothelial cells. CD90 can form dimers and higher order multimers. CD90 binds to heparin, the proteoglycan Syndecan4, and Integrins including αMβ2, αVβ3, and αVβ5. Through these interactions, CD90 inhibits neurite outgrowth, promotes astrocyte adhesion, mediates the extravasation of leukocytes and melanoma cells, supports the Thrombospondin1 induced disassembly of fibroblast focal adhesions, and inhibits the activation of myofibroblast differentiation and lung fibrosis. CD90 may be a prognostic marker for Neuroblastoma (NBL) which is the most common solid tumor in children. CD90 may also play an important role in cell-cell or cell-ligand interactions during synaptogenesis and other events in the central nervous system.
