Related Product Information for IL7 active protein

IL7 is a secreted cytokine of the hemopoietin family that primarily affects early B and T cells and plays an important role in stimulating the proliferation of lymphoid progenitors. IL7 is produced by stromal epithelial cells of the thymus, bone marrow, and intestines. Human and murine IL7 share 60% sequence homology at the primary level and known to exhibit cross species activity. Designated CD127, the human IL7 receptor is a strongly glycosylated membrane protein of 76 kDa. Recombinant Human IL7 is a 17.7 kDa, non-glycosylated protein.

NCBI Description

The protein encoded by this gene is a cytokine important for B and T cell development. This cytokine and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. This cytokine is found to be a cofactor for V(D)J rearrangement of the T cell receptor beta (TCRB) during early T cell development. This cytokine can be produced locally by intestinal epithelial and epithelial goblet cells, and may serve as a regulatory factor for intestinal mucosal lymphocytes. Knockout studies in mice suggested that this cytokine plays an essential role in lymphoid cell survival. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional splice variants have been described but their presence in normal tissues has not been confirmed.[provided by RefSeq, Dec 2010]

Uniprot Description

IL7: Hematopoietic growth factor capable of stimulating the proliferation of lymphoid progenitors. It is important for proliferation during certain stages of B-cell maturation. Belongs to the IL-7/IL-9 family. 2 isoforms of the human protein are produced by alternative splicing.
