NCBI Summary for CD28
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]
UniProt Comments for CD28
CD28: a type I plasma membrane protein Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. Binds to B7-1 and -2. Expressed in T cells and plasma cells, but not in less mature B cells. Six splice-variant isoforms have been described.

Protein type: Membrane protein, integral; Cell surface

Chromosomal Location of Human Ortholog: 2q33

Cellular Component: integral to plasma membrane; plasma membrane; immunological synapse; cytosol; external side of plasma membrane
