| abstractText | To understand better the regulation of interleukin-5 receptor alpha-subunit (IL-5R alpha) expression, we have isolated the genomic clones of mouse IL-5R alpha (mIL-5R alpha) and analyzed the structure of the gene. The gene spans more than 35 kb and is composed of 11 exons. We found that two mRNAs encoding secreted forms of mIL-5R alpha result from differential splicing events. We identified the transcriptional start site by primer extension analysis of mIL-5R alpha mRNA. Nucleotide sequence of the 5'-flanking region contains potential binding sites for transcription factor Ap1, AP-1, GATA-1, and PU.1. About 260 bp sequence of the 5'-flanking region exhibited promoter activity when it was linked to a promoterless bacterial chloramphenicol acetyltransferase (CAT) gene. The promoter activity was seen not only in the IL-5-dependent pre-B-cell line Y16, but also in fibroblast cell line NIH-3T3. Comparison of the exon-intron boundaries of mIL-5R alpha genes with those of other members of the cytokine receptor family reveals a conserved evolutionary structure. By fluorescence in situ hybridization analysis, the mIL-5R alpha gene has been assigned to chromosome 6. |
