IL-20R beta Protein, Cynomolgus (HEK293, Fc)

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, His) is produced in HEK293 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].
