Molecular classification
Receptor, Interleukin-10 Receptor Family, Cytokine Receptor
01

Overview

The Interleukin-20 receptor (IL-20R) is a heterodimeric receptor belonging to the IL-10 receptor family. It exists in two forms, Type I (IL20RA + IL20RB) and Type II (IL22RA1 + IL20RB), and binds to interleukins 19, 20, and 24. Signaling primarily occurs through the JAK-STAT pathway, influencing epithelial cell proliferation, wound healing, inflammation, and other processes. Dysregulation of IL-20R signaling is implicated in diseases like psoriasis, rheumatoid arthritis, atherosclerosis, and cancer.
