IL-3 Protein, Human (Biotinylated, Avi)
IL-3 protein is mainly secreted by T lymphocytes, mast cells and osteoblasts and is critical for the generation and differentiation of hematopoietic progenitor cells. It stimulates mature basophils, eosinophils and monocytes, promoting functional activation. IL-3 Protein, Human (Biotinylated, Avi) is the recombinant human-derived IL-3 protein, expressed by E. coli , with N-Avi labeled tag.

Description

It stimulates mature basophils, eosinophils and monocytes, promoting functional activation. IL-3 Protein, Human (Biotinylated, Avi) is the recombinant human-derived IL-3 protein, expressed by E. coli , with N-Avi labeled tag.
Background
The cytokine IL-3, predominantly secreted by activated T-lymphocytes, mast cells, and osteoblastic cells, plays a crucial role in controlling the production and differentiation of hematopoietic progenitor cells into lineage-restricted cells. Additionally, IL-3 stimulates mature basophils, eosinophils, and monocytes, promoting their functional activation. Beyond its hematopoietic functions, IL-3 contributes to neural cell proliferation and survival. Moreover, it participates in bone homeostasis by inhibiting osteoclast differentiation through the prevention of NF-kappa-B nuclear translocation and activation. Mechanistically, IL-3 exerts its biological effects through a receptor composed of the IL3RA subunit and the signal transducing subunit IL3RB. Stimulation of this receptor leads to the rapid activation of JAK2 kinase activity, initiating a STAT5-mediated transcriptional program. Alternatively, IL-3 contributes to cell survival under oxidative stress in non-hematopoietic systems by activating pathways mediated by PI3K/AKT and ERK. The cytokine also interacts with IL3RA to modulate its diverse physiological effects.
