Abstract

The mouse UGRP gene family consists of two genes, Ugrp1 and Ugrp2. In this study, the genomic structure and expression patterns of Ugrp2 and its alternative spliced form were characterized. The authentic Ugrp2 gene has three exons and two introns, similar to the Ugrp1 gene, which produces a secreted protein. The Ugrp2 variant uses a sequence located between authentic exons 1 and 2, resulting in a cytoplasmic form due to a termination codon within the inserted sequence. Both mouse and human UGRP2 mRNAs are expressed in lung. In the case of human, the mRNA is expressed at the highest level in trachea, followed by salivary gland at a level similar to lung. Weak expression was also found in fetal lung and mammary gland. Ugrp2 was mapped by fluorescence in situ hybridization to mouse chromosome 11A5-B1 and human chromosome 5q35. These regions are known to be homologous. Interspecific mouse backcross mapping was also performed to obtain further detailed localization of mouse Ugrp1 and Ugrp2.
