IRP1

IRP1, also known as Interleukin-1 Receptor-like Protein 1, is a protein that in humans is encoded by the IRP1 gene. This gene is located on chromosome 19q13.3. IRP1 is a member of the interleukin-1 receptor family and is involved in the regulation of cell growth and differentiation. It plays a crucial role in the development of the immune system and is expressed in various tissues, including the liver, kidney, and pancreas.

IRP1 is a type I transmembrane protein with a short cytoplasmic domain and a long extracellular domain. The extracellular domain contains several conserved motifs that are characteristic of the interleukin-1 receptor family. These motifs are involved in ligand binding and signal transduction. IRP1 can bind to several ligands, including interleukin-1 beta (IL-1β) and interleukin-18 (IL-18), which are pro-inflammatory cytokines.

The signaling pathway initiated by IRP1 involves the activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B (NF-κB). These signaling pathways are involved in the regulation of gene expression and the induction of inflammatory responses. IRP1 has been shown to play a role in the pathogenesis of various diseases, including inflammatory bowel disease, rheumatoid arthritis, and cancer.

In summary, IRP1 is a protein that belongs to the interleukin-1 receptor family and is involved in the regulation of cell growth and differentiation. It plays a crucial role in the development of the immune system and is expressed in various tissues. IRP1 can bind to several ligands and initiate signaling pathways that are involved in the regulation of gene expression and the induction of inflammatory responses.
