IL-20 Protein, Mouse (HEK293, His)

IL-20 Protein, a pro-inflammatory and angiogenic cytokine, is primarily secreted by monocytes and skin keratinocytes, and it serves crucial roles in immune responses, regulation of inflammatory responses, hemopoiesis, as well as epidermal cell and keratinocyte differentiation. This protein enhances tissue remodeling and wound-healing activities, playing a key role in maintaining the integrity of epithelial layers during infection and inflammatory responses. IL-20 Protein affects various actin-mediated functions in activated neutrophils, leading to the inhibition of phagocytosis, granule exocytosis, and migration. Its effects are exerted through the type I IL-20 receptor complex (IL20RA and IL20RB) or the type II IL-20 receptor complex (IL22RA1 and IL20RB). Furthermore, IL-20 Protein activates a range of signaling processes, including phosphorylations of JAK2 and STAT5, as well as the activation of serine and threonine kinases AKT and ERK1/2. In keratinocytes, it can activate STAT3 phosphorylation and transcriptional activity in a JAK2, ERK1/2, and p38 MAPK-dependent manner. IL-20 Protein forms a 1:1:1 heterotrimeric complex with its primary high-affinity heterodimeric receptor IL20RA/IL20RB.
