IL-20: Proteins and Enzymes

Mature human and mouse IL-20 is a 152 amino acid protein that is not likely glycosylated. Although IL-20 is a distant member of the IL-10 family, it functions as a monomer. IL-20 binds two heterodimeric receptor complexes, IL-20 R alpha/IL-20 R beta and IL-22 R/IL-20 R beta. IL-20 is reported to induce the proliferation of multipotential hematopoietic progenitor cells, direct the differentiation and expansion of keratinocytes, and promote the release of proinflammatory mediators in keratinocytes and other IL-20 receptor-expressing cells.
