IL20 Recombinant Human Protein Gibco™

Recombinant IL20 is a bioactive protein intended for use in cell culture applications. There are two heterodimeric receptor complexes for IL20. The first is composed of IL20 Ra and IL20 Rb. The second is composed of IL-22 R and IL20b. IL20 induces the proliferation of multipotential hematopoietic progenitor cells, directs the differentiation and expansion of keratinocytes, and promotes the release of proinflammatory mediators in keratinocytes and other cells expressing the IL20 receptor.

Background
Human epidermal growth factor (EGF) exerts actions on a wide variety of biological processes, and plays an important role in the regulation of cell growth, proliferation, and differentiation mediated by its high-affinity receptor EGFR on the cell surface. It induces differentiation of specific cells, promotes angiogenesis, and inhibits gastric acid secretion in vivo, while serves as a potent mitogenic actor for a variety of cultured cells of both ectodermal and mesodermal origin. Human EGF was originally isolated from urine based on its inhibitory effect on gastric secretion and named urogastrone accordingly. EGF is the founding member of the EGF-family of proteins which are characterized by the presence of at least one EGF structural unit (a conserved 6 cysteine motif that forms three disulfide bonds). The EGF precursor is believed to exist as a membrane-bound molecule containing 9 EGF units, and is proteolyticallycleaved to generate the 53-amino acid peptide hormone.
