to Ensure the continuity of the transmission of hereditary information from generation to generation is possible. This is the conclusion reached by scientists at the University of Edinburgh in Scotland, writes Nature.
Experts have found that germ cells in developing embryos are protected from damage and ensures continuity of the transmission of hereditary information from generation to generation. A key role in protecting sperm from epigenetic reprogramming in the early stages of development plays a protein SPOCD1. It contributes to methylation, i.e., joining of DNA methyl groups, which allows you to block transposons. Also, this protein is associated with MIWI2 and small non-coding RNAS that play an important role in the regulation of transposons.
the experiments on mice showed that the loss of protein SPOCD1 laboratory mice begin to suffer from infertility.
