| Post Translational Modifications | Glycosylated. In testis there are two predominant forms of 77- and 67-kDa and a form of 47-kDa, whereas in epididymal sperm from caput, corpus, and cauda there are two forms of 47- and 43-kDa. Testis forms contain complex carbohydrate residues. Epididymal sperm forms are N-glycosylated. Then undergoes significant glycosylation in the testis and that the majority of these glycoconjugates are removed by the time sperm reach the caput epididymis. |
