    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • might be involved in the control of immunoglobulin E production
  • essential for allergen-induced airway hyperreactivity and mucus hypersecretion but not for fibroblast or alternative macrophage activation
  • can potentially regulates IL4-induced responses in the lung
  • essential for baseline IgE production, but Th2 and IgE responses to T cell-dependent antigens are IL13RA1-independent
  • central role for the IL13/IL13RA1 pathway in the regulation of intestinal epithelial cell Cl(-) secretion via up-regulation of CFTR, suggesting an important role for this pathway in secretory diarrhea
