Genome-wide identification of glutathione S-transferase (GST) gene family and its regulating characteristics responding to sperm capacitation in Eriocheir sinensis.

Sperm capacitation is regarded to be a process of redox regulation. Within the oxidative regulatory system, glutathione S-transferases (GSTs) are important in the maintenance of the redox balance of reactive oxygen species (ROS). We identify 56 GST genes in the Chinese mitten crab Eriocheir sinensis genome, and categorize them into 13 classes, of which the largest is Mu.
