Abstract

Bovine colostral odorant-binding protein (bcOBP) is a novel protein found in bovine colostrum and belonging to the lipocalin superfamily. Most of them are secretory proteins. We have examined the localisation of bcOBP messenger RNA in several tissues. The expression of bcOBP messenger RNAs was followed in bovine principal organs and female reproductive tracts with in situ hybridisation, but the localisation of it was not detected. The expression levels of bcOBP mRNAs were also extremely low in those tissues. On the other hand, the expression of bcOBP messenger RNAs has not been found in the airway epithelia and the gallbladder. These results suggest that bcOBP messenger RNAs are expressed in bovine several tissues without its localisation. In conclusion, the localisation of bcOBP messenger RNAs in bovine several tissues was not found.
