Protein names

T-cell-specific surface glycoprotein CD28 , TP44 , CD antigen CD28

Protein 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 . Isoform 3 enhances CD40L-mediated activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells .

Protein tissue specificity

Expressed in T-cells and plasma cells, but not in less mature B-cells.

Protein sequence and domain

Contains 1 Ig-like V-type (immunoglobulin-like) domain.

Protein post-translational modifications

CD40LG induces tyrosine phosphorylation of isoform 3.

Protein cellular localization

Membrane; Single-pass type I membrane protein / Cell surface
