Alternate Names for IL-9 Antibody (222622)
IL-9homolog of mouse T cell and mast cell growth factor 40
p40 T-cell and mast cell growth factor
T-cell growth factor P40
IL-9 was originally identified as a T cell-derived T cell growth factor
III/P40 which could support the long term growth of certain mouse T
helper clones in the absence of antigen or antigen-presenting cells.
IL-9 can also prolong the in vitro survival of other T cell
clones as well as potentiate the IL-2 dependent proliferation of mouse
fetal thymocytes. However, this cytokine has no growth-stimulating
activity on mouse cytolytic T cell clones or fresh T cells. Mouse IL-9
also has mast cell enhancing activity (MEA) and can enhance the mIL-3-
or mIL-4-dependent proliferation of mouse bone marrow-derived mast
cells. Furthermore, IL-9 will synergize with erythropoietin to support
erythroid colony formation in vitro. The mouse IL-9 cDNA
encodes a 144 amino acid residue precursor protein with an 18 amino acid
signal peptide that is cleaved to form the mature cysteine-rich protein
with a predicted molecular mass of 14 kDa. Mouse IL-9 contains four
potential N-linked glycosylation sites and the native mIL-9 is a highly
glycosylated protein. Human and mouse IL-9 share 56% amino acid sequence
homology. Although mouse IL-9 is active on human cells, human IL-9 is
not active on mouse cells.
