IL-17RD Protein, Human (283a.a, HEK293, His)

Cat. No.: HY-P72578
Handling Instructions

Interleukin-17 receptor D (IL-17RD) also known as Sef (similar expression to fibroblast growth factor), is a type I transmembrane protein that can regulate several signaling pathways. Within the cell, IL-17RD expression has been localized mainly to the plasma membrane. IL-17RD is a feedback inhibitor of fibroblast growth factor (FGF) signaling. IL-17RD Protein, Human (283a.a, HEK293, His) is produced in HEK293 cells with six C-Terminal His-tags. It consists of 283 amino acids (C17-R299).

Description

Interleukin-17 receptor D (IL-17RD) also known as Sef (similar expression to fibroblast growth factor), is a type I transmembrane protein that can regulate several signaling pathways. Within the cell, IL-17RD expression has been localized mainly to the plasma membrane. IL-17RD is a feedback inhibitor of fibroblast growth factor (FGF) signaling[1]. IL-17RD Protein, Human (283a.a, HEK293, His) is produced in HEK293 cells with six C-Terminal His-tags. It consists of 283 amino acids (C17-R299).

Background

IL-17RD is a type I transmembrane protein that is evolutionarily conserved among vertebrates and is encoded by a single locus on chromosome 3p14.3 in humans. Within the cell, IL-17RD expression has been localized mainly to the plasma membrane although its expression has also been observed in the Golgi apparatus and in early and recycling endosomes (perinuclear structures) in overexpression systems[1].
The amino acid sequence of human IL-17RC protein shares 87% homology with mouse IL-17C protein.
Structurally, human IL-17RD is encoded by a single locus on chromosome 3p14.3 in humans. The mRNA consists of 13 exons encoding a polypeptide product of 739 amino acids comprised of a 26-residue amino terminal signal peptide, followed by a 272 amino acid extracellular domain, a short transmembrane domain consisting of 20 amino acids, and a 420 amino acid intracellular domain. The extracellular domain of IL-17RD consisting of a signal peptide, an immunoglobulin-like domain and a fibronectin type III repeat. Physiologically, IL-17RD has been shown to exist in monomeric, dimeric as well as oligomeric forms, showing a preference for oligomerization. In its dimeric form, SEF exists as a homodimer as well as in heterodimeric forms with FGFR1 (through its extracellular, transmembrane and intracellular domain), FGFR2 (via its extracellular, transmembrane and intracellular), IL-17RA (predominantly through its SEFIR domain), TNFR2 (via its extracellular domain) TLR3 (partly through its SEFIR domain) and TLR4 (partly through its SEFIR domain) and with Epidermal Growth Factor Receptor (EGFR)[1][2].
IL-17RD is initially established as a negative regulator of FGF-induced Ras and MAPK signalling pathways during zebrafish and frog development. It is subsequently determined to regulate other receptor tyrosine kinase signaling cascades as well as several proinflammatory signaling pathways including Interleukin-17A (IL17A), Toll-like receptors (TLR) and Interleukin-1α (IL1α) in several vertebrate species including humans. In addition, in mammalian IL-17RD can inhibit ERK and PI3K pathways in response to a number of receptor tyrosine kinase ligands. IL-17RD is a negative regulator of both NF-κB and IRF signalling pathways initiated by Toll-like receptors (TLRs). The SEFIR domain of IL-17RD targets the TIR adaptors, MyD88, Mal, TRIF and TRAM, and strongly inhibits TLR-mediated activation of NF-κB with IL-17RD deficiency leading to increased NF-κB and IRF activation and upregulation of pro-inflammatory genes. IL-17RD might regulate the activation of the TGFβ/BMP pathway. Additionally, the IL-17RD isoform is also shown to associate with and promote Lys63 polyubiquitination of TAK1 in HEK293T cells. IL-17RD promotes apoptosis by activating both p38 MAPK and JNK pathways upon ultraviolet light exposure in an overexpression model. IL-17RD is involved in the regulation of cancer, neuroendocrine, inflammatory and immunomodulatory diseases[1][2].

In Vitro

Co-transfection of HEK293 cells with IL-17RD (0-100 ng) caused a dose-dependent inhibition of MyD88-, Mal-, TRIF- and TRAM-mediated induction of NF-κB-regulated luciferase[2].
qRT-PCR and ELISA analyses show that the levels of IL-17RD (500 nM, 1 μM, and 2 μM; 3-18 hours) and TNF-α synergistically increases the mRNA and protein levels of IL-6 and TNF-α in bone marrow-derived macrophages (BMDMs), while sIL-17RD alone fails to induce these effects. IL-17RD enhances the TNF-α-induced proinflammatory response by increasing TNF-α signaling in BMDMs[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
