Recombinant Mouse B7-2 Protein, hFc Tag

Molecular Characterization: Mouse B7-2 (Val24-Glu245) hFc (Glu99-Ala330) Molecular weight: The protein has a predicted molecular mass of 51.4 kDa after removal of the signal peptide. The apparent molecular mass of mB7-2-hFc is approximately 55-70 kDa due to glycosylation.Description: Recombinant mouse B7-2 protein with C-terminal human Fc tagThis gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.
