In vitro analysis in MLE cells revealed that Il3 augmented proinflammatory cellular responses to lipopolysaccharide (LPS) through Rnft2 and Il3ra, as LPS sensitized cells to Il3 through stabilization of Il3ra. Mutation analysis identified lys357 of Il3ra as a critical residue for regulation of its stability, as lys357 mutants were resistant to Rnft2-directed degradation. Analysis with a mouse model for pneumonia and severe lung injury found that Il3 drove inflammation in LPS-induced lung injury in vivo, and further analysis revealed that lung inflammation was regulated through the Rnft2/Il3ra/Il3 axis. Moreover, analysis with parenchymal explant lung samples from human cystic fibrosis (CF; <a href="/entry/219700">219700</a>) patients showed that the RNFT2/IL3RA/IL3 axis was also involved in human inflammatory lung disease. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=31990690" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<p>The receptor for interleukin-3 (IL3; 147740) is a heterodimer that shares a beta chain (CSF2RB; 138981) in common with the receptors for IL5 (IL5RA; 147851) and GMCSF (CSF2RA; 306250), and, like these other cytokine receptors, has a ligand-specific alpha chain (IL3RA) (Kremer et al., 1993). </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Itoh et al. (1990) cloned IL3RA, a binding component of the IL3 receptor. Sequence comparison of the IL3 receptor with other cytokine receptors showed a common motif of a distinct receptor gene family. Kitamura et al. (1991) showed that the alpha chain for the IL3 receptor is a 360-amino acid glycoprotein of approximately 70 kD. </p>

<strong>Gene Function</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Kitamura et al. (1991) found that IL3RA alone bound human IL3 with extremely low affinity. A high affinity IL3-binding site was reconstituted by coexpressing IL3RA and CSF2RB, indicating that IL3R and CSF2RA share the same beta subunit. As in human hematopoietic cells, IL3 and GMCSF competed for binding in fibroblasts expressing the cDNAs for IL3RA, CSF2RA, and the common beta subunit, indicating that different alpha subunits compete for a common beta subunit. </p><p>Siracusa et al. (2011) demonstrated that TSLP (607003) promotes systemic basophilia, that disruption of TSLP-TSLPR (300357) interactions results in defective basophil responses, and that TSLPR-sufficient basophils can restore TH2-cell-dependent immunity in vivo. TSLP acted directly on bone marrow-resident progenitors to promote basophil responses selectively. Critically, TSLP could elicit basophil responses in both IL3-IL3R-sufficient and -deficient environments, and genomewide transcriptional profiling and functional analyses identified heterogeneity between TSLP-elicited versus IL3-elicited basophils. Furthermore, activated human basophils expressed TSLPR, and basophils isolated from eosinophilic esophagitis (see 610247) patients were distinct from classical basophils. Siracusa et al. (2011) concluded that collectively, their studies identified previously unrecognized heterogeneity within the basophil cell lineage and indicated that expression of TSLP may influence susceptibility to multiple allergic diseases by regulating basophil hematopoiesis and eliciting a population of functionally distinct basophils that promote TH2 cytokine-mediated inflammation. </p><p>By overexpression analysis in mouse lung epithelial (MLE) cells, Tong et al. (2020) showed that Rnft2 (620254) negatively regulated Il3ra stability through ubiquitination and proteasomal degradation in response to Il3 signaling. Rnft2 affected Il3ra abundance and signaling in response to Il3 by associating with Il3ra and targeting it as a substrate. In vitro analysis in MLE cells revealed that Il3 augmented proinflammatory cellular responses to lipopolysaccharide (LPS) through Rnft2 and Il3ra, as LPS sensitized cells to Il3 through stabilization of Il3ra. Mutation analysis identified lys357 of Il3ra as a critical residue for regulation of its stability, as lys357 mutants were resistant to Rnft2-directed degradation. Analysis with a mouse model for pneumonia and severe lung injury found that Il3 drove inflammation in LPS-induced lung injury in vivo, and further analysis revealed that lung inflammation was regulated through the Rnft2/Il3ra/Il3 axis. Moreover, analysis with parenchymal explant lung samples from human cystic fibrosis (CF; 219700) patients showed that the RNFT2/IL3RA/IL3 axis was also involved in human inflammatory lung disease. </p>

<strong>Gene Structure</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Kosugi et al. (1995) cloned the IL3RA gene which spans about 40 kb and has 12 exons. The genomic structures of IL3RA and CSF2RA are very similar and share an additional exon encoding part of the C-terminal domain not found in other members of this gene family. This suggested that the 2 loci may share a common evolutionary pathway. </p>

<strong>Mapping</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Kremer et al. (1993) found that the gene for the IL3 receptor, like the CSF2RA gene, maps within the X-Y pseudoautosomal region (PAR) (see 430000 for Y-chromosomal IL3RA). Kremer et al. (1993) mapped the gene to the X and Y chromosomes by PCR analysis of human/rodent somatic cell hybrids and to chromosomes Yp13.3 and Xp22.3 by fluorescence in situ hybridization. The pseudoautosomal location of IL3R was confirmed by screening of 2 informative CEPH families showing male meiotic recombination with respect to RFLPs. Using long-range restriction mapping, they found, furthermore, that IL3RA maps to the same 190-kb restriction fragment as CSF2RA, suggesting that a cytokine receptor gene cluster may reside in the PAR. </p><p>Milatovich et al. (1993) independently mapped the IL3RA gene to the X-Y pseudoautosomal region near the CSF2RA gene. Their methods were Southern analysis of somatic cell hybrid panels, pulsed field gel electrophoresis, and fluorescence chromosomal in situ hybridization. The CSF2RA and IL3RA genes were so close that their order could not be determined by two-color interphase in situ hybridization. Pseudoautosomal inheritance was demonstrated by an EcoRI RFLP detected with the IL3RA cDNA probe; 16 of 17 unrelated individuals of both sexes were heterozygous. They cited unpublished data indicating that the murine Il3ra locus maps to chromosome 14. Milatovich et al. (1993) found that the CSF2RA and IL3RA genes shared PFGE fragments generated by different restriction enzymes down to the 50- to 100-kb size range. </p>
