Target Details for CD28

Target: CD28

Alternative Name: CD28 (CD28 Products)

Background: CD28 acts as the ligand for the B7/BB-1 Molecule on the surface of activated B cells. B7/BB-1 costimulates T cells through CD28, along with CD2 and CD3. CD28 antigen is a disulfide-linked homodimeric glycoprotein. The CD28 antigen is present on approximately 60 % -80 % T lymphocytes (95 % of CD4 and 50 % of CD8 lymphocytes). CD28 regulates the expression of cytokines by T cells, not only IL-2, but also IL-1 alpha and CSF-1, usually synthesized by accessory cells. CD28 functions as a cell adhesion molecule (CAM) for certain T cell subsets.Synonyms: T-cell-specific surface glycoprotein CD28, TP44

Molecular Weight: 25.2kDa (NP_031668.3).
