| 研究领域 | Cancer > Tumor immunology > CD markers Immunology > Adaptive Immunity > T Cells > CD Immunology > Adaptive Immunity > T Cells > Cytotoxic Cells |
| 亚基 | In general heterodimer of an alpha and a beta chain linked by two disulfide bonds. Can also form homodimers. |
| 亚细胞定位 | Membrane; Single-pass type I membrane protein. |
| 组织特异性 | Most prominently found in the gastrointestinal tract, skin, lung, and brain but not in liver. |
| 相似性 | Contains 1 Ig-like V-type (immunoglobulin-like) domain. |
| 功能 | Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains. |
| 保存条件 | Shipped at 4℃. Store at -20℃ for one year. Avoid repeated freeze/thaw cycles. |
| 背景资料 | The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen acts as a coreceptor with the T-cell receptor on the T lymphocyte to recognize antigens displayed by an antigen presenting cell in the context of class I MHC molecules. The coreceptor functions as either a homodimer composed of two alpha chains or as a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 alpha chain. Multiple transcript variants encoding different isoforms have been found for this gene. The major protein isoforms of this gene differ by the presence or absence of a transmembrane domain and thus differ in being a membrane-anchored or secreted protein. [provided by RefSeq, May 2020] |
