Expression, localization, and function of P4HB in the spermatogenesis of Chinese mitten crab (Eriocheir sinensis) by Yulian Tang, Anni Ni, Shu Li, Lishuang Sun, Genliang Li

“…Conclusion P4HB was expressed in the testis tissues of both adult and juvenile E. sinensis, but the expression and localization were different in male germ cells at various developmental stages. The observed differences in the expression and localization of P4HB may be an essential factor in maintaining the cell morphology and structure of diverse male germ cells in E. sinensis. …”
