... exhibiting differential phosphorylation, on 59 specific amino acids, suggesting that modification of these particular sites is essential for the capacitation process. The relative ratio of phosphorylation between the capacitated and noncapacitated samples were also reported, providing the first biochemical ...

Protein translation in sperm

... report, Drs. Gur and Breitbart demonstrate that human, rat, bovine and mouse sperm all incorporate labeled amino acids into polypeptides during the capacitation phase. They identify that mitochondrial translation machinery (as opposed to cytoplasmic) directs translation of nuclear-encoded genes in sperm, and ...
