Gene Information

mouse ... Il1rl1(17082)

General description

ST2 (suppression of tumorigenicity) belongs to the IL-1 family of cytokines. It is also known as IL-33 (interleukin 33) and IL1RL1 (interleukin 1 receptor like 1). It is expressed in macrophages and various inflammatory cells like T helper 2 (Th2), mast cells, basophils and eosinophils. It is mapped to chromosome 2q12.


a synthetic peptide corresponding to 16 amino acids at the amino-terminus of mouse ST2. This peptide is common to all three known ST2 isoforms.


Anti-ST2 has been used in immunohistochemistry, western blottingand immunofluorescence staining.

Biochem/physiol Actions

ST2 (suppression of tumorigenicity) participates in pathophysiology of several diseases like asthma, arthritis, obesity and atherosclerosis. It works as a mitogen in eosinophils, fibrocytes, endothelial cells. It helps in the migration of Th2 lymphocytes, fibrocytes and endothelial cells, and disturbs the incursion and metastasis of breast tumor.


The action of this antibody can be blocked using blocking peptide SBP3363.

Interleukin-33 (IL-33) promotes migration of cancer cells through downregulating the expression of E-cadherin. Previous studies have demonstrated that IL‑33 stimulates the proliferation of trophoblasts. However, the effect of IL‑33 on the adhesion and invasion of trophoblasts has not been investigated...

Inflammatory bowel diseases (IBD) have been intrinsically linked to a deregulated cytokine network, but novel therapeutic principles are urgently needed. Here we identify the interleukin (IL)-33 and its receptor ST2 as key negative regulators of wound healing and permeability in...
