..Furthermore, we confirm the importance of CNNM4 in sperm by generating germ-cell-specific Cnnm4-deficient mice. These results suggest a new role of CNNM4 in sperm Ca(2+) homeostasis. ..

..Thus, sperm motility and Ca(2+) response were more severely affected in sperm from Cnnm2(+/?); Cnnm4(?/?) mice than in those from Cnnm4(?/?) mice, implicating CNNM2 in regulating these processes. ..
