Aberrant Distribution of ADAM3 in Sperm from Both Angiotensin-Converting Enzyme (Ace)- and Calmegin (Clgn)-Deficient Mice
Biol Reprod 2006 75: 760-766. [Abstract] [Full Text] [PDF]  

Summary: ADAM3 was absent from Clgn-/- sperm and was significantly decreased in the "detergent-enriched" fraction of Ace-/- sperm using Triton X-114, indicating that the ability of sperm to bind the zona pellucida could be explained by the amount of ADAM3.

Biol Reprod 2006 75: 785-791. [Abstract] [Full Text] [PDF]  

Summary: Telomerase reverse transcriptase (TERT) expression plays an important role in regulation of the enzyme telomerase in primordial germ cells, although modulation of TERT expression has no overt, short-term effect on primordial germ cell behavior
