SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	stimulating PDE7 for T cell activation and required for the formation of the mature immunologic synapse
	CD28 and ICOS play complementary non-overlapping roles in the development of Th2 immunity

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component	component of costimulatory signal, with B7-1 (MIC17/CD80) and BF-2 (CD86)
	homodimer disulfide-linked
	CD3D/CD28-inducible FAU/BCL2L14 complex may be involved in the regulation of T cell function and survival

INTERACTION

DNA

RNA

small molecule

protein	CD80, CD86 ligand, PRKCQ (within the immunologic synapse)
	HNRNPLL expression is dependent on CD28 signaling, providing a mechanism by which CD28 can regulate splicing in T cells and insight into how HNRNPLL can influence signal-induced alternative splicing in T cells
	enforces a requirement for CD28 costimulation by limiting IL2 production
	CARMIL2 is essential for CD28 co-stimulation in human T cells

REGULATION

Other

Susceptibility

to celiac disease to unexplained pregnancy loss

Variant & Polymorphism other	imbalance in CTLA4/CD28 expression or suppressed T-cell activity at the maternal-fetal interface may confer susceptibility to unexplained pregnancy loss
