Ovine and rat salivary gland mRNAs have been prepared and their translation products characterized. A 60 kD translation product from ovine submaxillary and sublingual gland mRNAs is identical in mass to the ovine apomucin. Two additional ovine translation products, 25 and 40 kD, are specific to mucin-producing salivary glands. Four rat mRNA translation products are encoded by mucin-producing salivary glands (38, 44, 67, 69 kD). These polypeptides were not detected in the parotid gland mRNAs, a serous gland. Each of these products has a high level of [3H]serine incorporation, a characteristic of mucins. The nature of these products suggests that they are mucins or mucin-like and that their molecular weights should approximate that of the corresponding apomucins.
