IL-20R beta Protein, Rat (HEK293, His)
Based on 1 Customer Validation
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 308 amino acids (M1-T308) with a transmembrane domain (226-249 a.a.). IL-20R beta Protein, Rat (HEK293, Fc) is produced in HEK293 cells with a C-Terminal hFc-tag.

Biological Activity
Description
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 308 amino acids (M1-T308) with a transmembrane domain (226-249 a.a.). IL-20R beta Protein, Rat (HEK293, Fc) is produced in HEK293 cells with a C-Terminal hFc-tag.
Background
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].
In Vivo
IL-2R beta/IL2RA is a receptor complex for IL-19. IL-2R beta is significantly up-regulated after IL-19 treatment (2 mg/kg; i.v. via tail wein; once daily for one week) in epidural fibrosis (EF) rats model[5].
rIL-19 treatment improved hematoma clearance and attenuated neurological deficits induced by GMH, which was mediated through the upregulation of the IL-2R1/ERK/Nrf2 pathways[6].
Verified Bioactivity
Measured by its binding ability in a functional ELISA. Immobilized Human IL-19, at 0.1 μg/mL (100 μL/well) can bind IL-20R beta. The ED50 for this effect is 28.75 ng/mL.
