|---|---|
| 基因名称 | Cd28 |
| 全名 | Cd28 molecule |
| 背景介绍 | CD28 is the critical T cell costimulatory receptor which provides to the cell the important second activation signal by binding CD80 and CD86 that are expressed by antigen presenting cells. Besides its costimulation role CD28 functions in preventing T cells from anergic hyporesponsive state or from undergoing premature apoptotic cell death. Its analog CTLA-4, expressed on the surface of activated T cells, has higher affinity to CD80 and CD86 than CD28 and downregulates T cell activity. |
| 生物功能 | Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. [UniProt] |
| 研究领域 | Developmental Biology antibody; Immune System antibody; Cytotoxic T Cell Surface Study antibody |
| 预测分子量 | 25 kDa |
| 翻译后修饰 | CD40LG induces tyrosine phosphorylation of isoform 3. |
