Uteroglobin mRNA from the lung of the hare (Lepus capensis): cell-free translation and properties.
Poly(A)-containing RNA was obtained from the lung of hares (Lepus capensis) and uteroglobin mRNA was characterized by cell-free translation and molecular hybridization to a rabbit uteroglobin cDNA probe. In the cell-free system, hare uteroglobin mRNA was preferentially translated as compared to the whole lung mRNA and it directed the synthesis of a precursor, preuteroglobin, containing about twenty additional amino acids. Hare uteroglobin mRNA was about 40 nucleotides larger than the homologous rabbit one, as analyzed by electrophoresis on agarose gel. Thermal stability of the hybrids formed between rabbit or hare uteroglobin mRNAs and the rabbit cDNA probe indicated differences in the nucleotide sequence of both mRNAs. The levels of uteroglobin mRNA and uteroglobin synthesis in lung are about two-fold higher in hare than in rabbit lung.
