Recombinant Human Interleukin-13V
IL13V
Interleukin 13 Variant
Human Interleukin-13 (IL13) is expressed by the IL13 gene located on the chromosome 5. IL13 is a 112 amino acid protein containing a proposed 20 amino acid signal peptide making it 132 amino acids total, and shares approximately 30% amino acid sequence homology to human IL4. Additionally, the two cytokines exhibit overlapping biological activities. Human IL13 is produced by activated Th0, Th1-like Th2-like and CD8 T-cells. Similarly to IL4, IL13 has multiple effects on the differentiation of monocytes/macrophages, and can suppress their cytotoxic functions.
IL13 variant is a natural variant of the wild-type IL13 as it has a Q110 (glutamine) instead of an R110 (arginine), which is associated with increased risk for asthma development. At homozygosity, IL13V is associated with higher levels of total serum IgE in some allergic rhinitis patients.
