EFCAB6 and Infertility: These proteins were mitochondrial citrate synthase (CISY), Dynein axonemal intermediate chain 1 (DNAI1), EF-hand calcium-binding domain-containing protein 6 (EFCB6), Golgi-associated RAB2 interactor protein 3 (GAR3), Leucine-rich repeat-containing protein 37B (LR37B) and Sperm equatorial segment protein 1 (SPESP), with the mean protein’s levels significantly lower in the infertile groups comparing to CTRL (Figure 7).
