Human Interleukin 7 (IL-7) is a potent lymphoid cell growth factor stimulating the proliferation of lymphoid progenitors. IL7 can associate with the hepatocyte growth factor (HGF) to form a hybrid cytokine that functions as a pre-pro-B cell growth-stimulating factor. Human IL7 cDNA encodes a 177 amino acid precursor protein containing a 25 amino acid signal peptide and a 152 amino acid mature protein. Human and mouse IL7 share 65% sequence identity in the mature region and both exhibit cross-species activity. IL-7 signals via IL-7 receptor (IL7R) activating multiple pathways including JaK STAT and PI3K AKT, which regulate lymphocyte survival, glucose uptake, proliferation, and differentiation. IL-7 is also associated with cytoplasmic IL2-R gamma for signal transduction.

Hematopoietic growth factor capable of stimulating the proliferation of lymphoid progenitors. It is important for proliferation during certain stages of B-cell maturation. IL-7 Protein, Bovine, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 21.3 kDa and the accession number is P26895.

Mouse interleukin-7(IL-7) is the member of hemopoietin family which is important to the differentiation, proliferation, and survival of lymphocyte. Mouse IL-7 shares approximately 88% aa sequence identity with rat IL-7 and 58-60% with human, equine, bovine, ovine, porcine, feline and canine IL-7. It is widely expressed in primary and secondary lymphoid tissues cell and stromal epithelial cells of the thymus, bone marrow, and intestines. IL-7 activation of IL-7 R alpha is critical for both T cell and B cell lineage development. It is important for proliferation during certain stages of B-cell maturation. IL-7 contributes to the maintenance of all naïve and memory T cells, mainly by promoting expression of the anti-apoptotic protein Bcl-2. It is required for optimal T cell-dendritic cell interaction.

IL-7 Protein, Rat, Recombinant is expressed in E. coli expression system. The predicted molecular weight is 15 kDa and the accession number is Q91Y32.

Transcriptional regulator which displays a remarkable functional diversity in the regulation of cellular responses. Regulates transcription of IFN and IFN-inducible genes, host response to viral and bacterial infections, regulation of many genes expressed during hematopoiesis, inflammation, immune responses and cell proliferation and differentiation, regulation of the cell cycle and induction of growth arrest and programmed cell death following DNA damage. Stimulates both innate and acquired immune responses through the activation of specific target genes and can act as a transcriptional activator and repressor regulating target genes by binding to an interferon-stimulated response element (ISRE) in their promoters. Competes with the transcriptional repressor ZBED2 for binding to a common consensus sequence in gene promoters. Its target genes for transcriptional activation activity include: genes involved in anti-viral response, such as IFN-alpha beta, DDX58 RIG-I, TNFSF10 TRAIL, ZBP1, OAS1 2, PIAS1 GBP, EIF2AK2 PKR and RSAD2 viperin; antibacterial response, such as NOS2 INOS; anti-proliferative response, such as p53 TP53, LOX and CDKN1A; apoptosis, such as BBC3 PUMA, CASP1, CASP7 and CASP8; immune response, such as IL7, IL12A B and IL15, PTGS2 COX2 and CYBB; DNA damage responses and DNA repair, such as POLQ POLH; MHC class I expression, such as TAP1, PSMB9 LMP2, PSME1 PA28A, PSME2 PA28B and B2M and MHC class II expression, such as CIITA; metabolic enzymes, such as ACOD1 IRG1. Represses genes involved in anti-proliferative response, such as BIRC5 survivin, CCNB1, CCNE1, CDK1, CDK2 and CDK4 and in immune response, such as FOXP3, IL4, ANXA2 and TLR4. Stimulates p53 TP53-dependent transcription through enhanced recruitment of EP300 leading to increased acetylation of p53 TP53. Plays an important role in immune response directly affecting NK maturation and activity, macrophage production of IL12, Th1 development and maturation of CD8+ T-cells. Also implicated in the differentiation and maturation of dendritic cells and in the suppression of regulatory T (Treg) cells development. Acts as a tumor suppressor and plays a role not only in antagonism of tumor cell growth but also in stimulating an immune response against tumor cells.
