The uterine milk proteins (UTM-proteins), a pair of basic glycoproteins with similar isoelectric points and molecular weights (57,000 and 55,000), are secreted by the endometrium of the pregnant ewe. Peptide mapping of the two species of UTM-proteins demonstrated them to be structurally related. Furthermore, pulse-chase and continuous-labeling experiments indicated that both are produced from a common precursor of lower molecular weight. Purified UTM-proteins were found to be rich in basic… CONTINUE READING
