| 产品编号 | KMP2865 |
|---|---|
| 产品名称 | Human CTLA-4 Protein, hFc Tag, Avi Tag |
| 产品描述 | The Human CTLA-4 Protein(KMP2865) is produced in HEK293 Cells. The target gene encoding the Human CTLA4 (NP_005205.2)(Met1-Phe162) is expressed with a c-terminal Avi tagged Fc region of human IgG1 at the C-terminus (Fc-Avi). The expressed protein is biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. |

| 产品背景 | Cytotoxic T-lymphocyte protein 4, also known as CTLA4 and CD152, is a single-pass type I membrane protein and a member of the immunoglobulin superfamily. It is the second member of the CD28 receptor family. The ligands or counterreceptors for these two proteins are the B7 family members, CD80 (B7-1) and CD86 (B7-2). CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T cells and may play an important role in their functions. CD152 or cytotoxic T lymphocyte antigen-4 (CTLA-4) is an essential receptor involved in the negative regulation of T cell activation. Because of its profound inhibitory role, CD152 has been considered a sound susceptible candidate in autoimmunity and a persuasive target for cancer immunotherapy. In particular, recent evidence suggests that CD152 is also important in the homeostasis and function of a population of suppressive cells, termed regulatory T cells (Treg). |
