Abstract/OtherAbstract:
|
The proteins that are neosynthesized and secreted in the different regions of the human epididymis were determined by in vitro biosynthesis of epididymal tubules, and the luminal proteins were collected by microperfusion of each tubule. The preparations were analyzed by two-dimensional gel electrophoresis and the proteins were identified by mass spectrometry. Some of the major proteins identified corresponded to serum compounds such as albumin, transferrin and alpha-1-antitrypsin. The other proteins identified included lactotransferrin, clusterin, PEBP, NCP2/CTP/HE1, HE3, Crisp, actin, calmodulin, E12, PGDS, l-lactate dehydrogenase, malate dehydrogenase, carbonic anhydrase, triose phosphate isomerase, glutamyltransferase, glutathione S-transferase P, thioredoxin peroxidase, superoxide dismutase, cathepsin D and cystatin. Epididymal activity is highly regionalized in most species. However, in this study in humans, there were only minor changes in the major proteins secreted. It is suggested that this specificity might be related to the difference between species in the location of the epididymis where sperm become fertile. |
