IL-5 Protein, Mouse (sf9, His)

IL-5 protein is expressed by T lymphocytes and NK cells and regulates eosinophils, affecting their survival, differentiation and chemotaxis. In addition, IL-5 stimulates immunoglobulin production, growth, and differentiation of activated and resting B cells. IL-5 Protein, Mouse (sf9, His) is the recombinant mouse-derived IL-5 protein, expressed by Sf9 insect cells , with C-His labeled tag.

IL-5 Protein, a homodimeric cytokine predominantly expressed by T-lymphocytes and NK cells, plays a pivotal role in the regulation of eosinophils by influencing their survival, differentiation, and chemotaxis. Additionally, IL-5 acts on both activated and resting B-cells, stimulating immunoglobulin production, growth, and differentiation. Mechanistically, the biological effects of IL-5 are mediated through a receptor complex composed of the IL5RA subunit and the cytokine receptor common subunit beta/CSF2RB. Upon binding to the receptor, IL-5 triggers the activation of various kinases, including LYN, SYK, and JAK2, thus propagating signals through the RAS-MAPK and JAK-STAT5 pathways (By similarity). Structurally, IL-5 forms a homodimer that is disulfide-linked and interacts with its receptor components IL5RA and CSF2RB, highlighting the specificity and complexity of its molecular interactions in orchestrating immune responses.
