title: MSY2 and polypyrimidine tract binding protein 2 stabilize mRNAs in the mammalian testis.
abstract: MSY2 is a highly conserved and abundant DNA/RNA-binding protein that functions as a global stabilizer/translational suppressor of mRNAs in male germ cells. The polypyrimidine tract binding protein, PTBP2, is an RNA-binding protein that splices nuclear transcripts and stabilizes specific mRNAs in the cytoplasm. The mechanisms whereby MSY2 selects and stabilizes a large group of male germ cell mRNAs and PTBP2 stabilizes specific mRNAs such as the phosphoglycerate kinase 2 mRNA in the testis and in transfected cells will be discussed.
