If any part of this process goes awry, the cells cannot mature into sperm. Researchers in the UC Davis College of Biological Sciences have now identified an important link in this process — a little-known protein called ATF7IP2.</span></p> February 21, 2024 - 3:20pm Andy Fell /blog/protein-integral-sperm-development-and-male-fertility-identified
