Bioinformation
| Gene Symbol | CD28 |
|---|---|
| Gene Full Name | CD28 molecule |
| Background | The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2011] |
| Function | Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. Enhances the production of IL4 and IL10 in T-cells in conjunction with TCR/CD3 ligation and CD40L costimulation (PubMed:8617933). Isoform 3 enhances CD40L-mediated activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells (PubMed:15067037). [UniProt] |
| Cellular Localization | Membrane; Single-pass type I membrane protein. Isoform 3: Cell surface. [UniProt] |
| Calculated MW | 25 kDa |
| PTM | CD40LG induces tyrosine phosphorylation of isoform 3. [UniProt] |
