It is the ligand for two different proteins on the T cell surface: CD28 and CTLA-4. Studies have shown that CTLA-4 binds mostly to CD80. The structure presents two extracellular domains: a membrane distal variable-like domain (IgV) and a membrane proximal Ig constant-like domain (IgC) along with an intracellular domain. Both IgV and IgC consist of anti-parallel beta sandwiches joined by a short linker region. CD80 is mostly expressed on the surface of antigen-presenting cells including activated B cells, macrophages and dendritic cells.\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48647903150180,"sku":"EPT046","price":131.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_8cf1dd8c-afe7-4e51-9c8e-1f58c9a00267.jpg?v=1782704401","url":"https:\/\/www.genebiosystems.com\/en-gb\/products\/recombinant-human-b7-1-c-6his","provider":"GeneBio ","version":"1.0","type":"link"}
