Resumo: | Using a combination of PAGE and mass spectrom etry for protein identification，we obtained evidence that a putative odorant-binding protein，designated hypothetical protein LOC517854，occurs in bovine colostrum. This protein，termed as a putative bovine colostral odorant-binding protein (bcOBP)， consists of 172 AA residues，including a putative 16-AA signal peptide. The theoreticalis oelectric point value and molecular mass of the full-length sequence of bcOBP were calculated to be 4.57 and 19604.18，respectively. The highest sequence similarity (83%) was observed with a potential pheromone transporter，Allergen Bos d 2. An odorant-binding protein derived from bovine nasal mucosa showed relatively low sequence similarity(52%) against bcOBP. Its biological function is  unclear，but pheromone transport could be considered. This is the first report of a putative odorant-binding protein in bovine colostrnm.
