Gene Information

human ... IL2(3558)

General description

IL-2 (interleukin 2) is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. It is a type I cytokine. Recombinant human IL-2 is a 15.5kDa protein, containing 134 amino acid residues including one intrachain disulfide bond.
The IL-2 gene is mapped to human chromosome 4q27.


IL-2 (interleukin 2) human has been used for the stimulation of human primary naive T lymphocytes to study the effect of microRNA-146a on IL-2 activation-induced cell death.

Biochem/physiol Actions

IL-2/IL-2R (interleukin 2/IL-2 receptor) signaling is required for T-cell proliferation and other fundamental functions which are essential for the immune response. IL-2 stimulates growth and differentiation of B-cells, NK (natural killer) cells, lymphokine activated killer cells, monocytes, macrophages and oligodendrocytes. It is associated with recurrent oral ulcer and asthma and Mycoplasma pneumoniae infection in children. Absence of IL-2 in mice causes fatal lymphoproliferative inflammatory disease (IL-2 deficiency syndrome). IL-2 signaling involves three pathways: phosphoinositol 3-kinase (PI3-K)/AKT, Ras-MAPK (mitogen activated protein kinase), and JAK-STAT (Janus kinase - signal transducers and activators of transcription) pathways.
