IL-20R beta Protein, Human (sf9, His)
IL-20R beta Protein (IL20RB) is the beta subunit of IL-20 receptor, forms functional heterodimers with different subunit protein and involves in STAT3 activation pathway. The IL-20RA/IL-20RB dimer is a receptor for IL-19, IL-20 and IL-24. The IL-22RA1/IL-20RB dimer is a receptor for IL-20 and IL-24. IL-20R beta Protein is consists of 311 amino acids (M1-S311) with a transmembrane domain (234-254 a.a.). IL-20R beta Protein, Human (sf9, His) is produced in Sf9 insect cells with a C-Terminal His-tag.

IL-20R beta Protein (IL20RB) is the beta subunit of IL-20 receptor, forms functional heterodimers with different subunit protein and involves in STAT3 activation pathway[1]. The IL-20RA/IL-20RB dimer is a receptor for IL-19, IL-20 and IL-24. The IL-22RA1/IL-20RB dimer is a receptor for IL-20 and IL-24[2]. IL-20R beta Protein is consists of 311 amino acids (M1-S311) with a transmembrane domain (234-254 a.a.). IL-20R beta Protein, Human (sf9, His) is produced in Sf9 insect cells with a C-Terminal His-tag.
IL-20R beta (IL-12RB), also known as a beta subunit of IL-20 receptor (IL-20RB), belongs to the type II cytokine receptor family. IL-20R beta is widely expressed with highest levels in skin and testis and highly expressed in psoriatic skin[1].
IL-20R beta forms functional heterodimers with different subunit protein. IL-20R beta serves as the receptor for IL-19, IL-20 and IL-24 by dimerizing with IL20RA, however serves as the receptor for IL-20 and IL-24 by dimerizing with IL-22RA1[2].
IL-20RB/IL-20RA and IL-20RB/IL-22RA1, act function by binding IL-20, and then stimulates a signal transduction pathway through STAT3 in a keratinocyte cell line[1].
However, the expression of both IL-20RB/IL-20RA is found to be upregulated in psoriatic skin lesions on keratinocytes[3].
IL-20RB/IL-20RA and IL-20RB/IL-22RA1 bind to IL-24, induce rapid activation of Stat-1 and Stat-3 transcription factors, which appear to play a role in cell survival and proliferation[4].
The sequence of amino acids in IL-12 beta proteins of human is very different from mouse (64.64%).
IL-2R beta involves in making up IL-2 II cytokine heterodimeric receptor type 1 (IL-2RB/IL-2RA) and type 2 (IL-2RB/IL-22RA1), thus binds to MDA-7 protein, encoded by melanoma differentiation-associated gene-7 (mda-7/IL24)[5].
Both type 1 and type 2 IL-2R binds to MDA-7 protein and induces phosphorylation and nuclear translocation of STAT3 in melanoma cells, also induces dose-dependent cell death in melanoma tumor cells, results in up-regulation of BAX and subsequent apoptosis induction[5].
