Purification, secretion and immunocytochemical localization of the uterine milk proteins, major progesterone-induced proteins in uterine secretions of the sheep.
Restriction of the conceptus to one uterine horn of the pregnant ewe results in the accumulation of fluid called uterine milk (UTM) in the contralateral horn. Two basic polypeptides, called the uterine milk proteins (UTM-proteins; Mr = 55,000 and 57,000 as determined by polyacrylamide-gel electrophoresis using sodium dodecyl sulfate), accounted for the majority of the protein in uterine milk. T...
متن کاملHealth-Related Aspects of Milk Proteins
Milk is an important component of a balanced diet and contains many valuable constituents. A considerable part of the milk healthbenefits is related to its proteins, not only for their nutritive value but also for their biological properties. Scientific evidence suggests that anticarcinogenic activities, antihypertensive properties, immune system modulation, and other metabolic features of milk...

متن کاملBiochemical characterization and biosynthesis of the uterine milk proteins of the pregnant sheep uterus.
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...
متن کاملPresence of the major progesterone-induced proteins of the sheep endometrium in fetal fluids.
Allantoic and amniotic fluids were collected on Days 60 (n = 3), 100 (n = 4), and 140 (n = 3) of pregnancy. The presence of uterine milk proteins (UTM-proteins) in these samples was evaluated by Ouchterlony immunodiffusion and enzyme-linked immunoabsorbant assay (ELISA). Eight of ten samples of allantoic fluid and three of ten samples of amniotic fluid produced one or two immunoprecipitin bands...
