The role of the polymeric receptor (pIgR) is to transport polymeric IgA across various mucosal epithelial layers. Although several mammalian pIgR cDNAs, including mouse, have been cloned, genomic structure has only been partially analyzed in the human, and neither its 5′-upstream region nor its transcriptional start site is known. We report the isolation and characterization of the murine pIgR gene that spans 32kb and contains 11 exons. The general organization of the murine gene, including its intron/exon boundaries was similar to its human homolog; however, the second intron was 7.2kb in the mouse vs. only 0.8kb in humans. Primer extension and 5′-RACE independently identified the identical transcriptional initiation site. Sequence analysis of 350 base pairs in the 5′-flanking region revealed several motifs, including a TATA box, and putative interferon-γ, HNF-3β and AP1 sites. In summary, we have isolated the murine pIgR gene and described its structure and organization.
