Meanwhile, to elucidate the conservation of IL-1R, its orthologous were identified in several crustacean species as well.

Sperm acrosomal released proteome reveals MDH and VDAC3 from mitochondria are involved in acrosome formation during spermatogenesis in Eriocheir sinensis.

Acrosome is inextricably related to membranous organelles. The origin of acrosome is still controversial, one reason is that limited articles were reported about the proteomic analysis of the acrosome. Mitochondrial proteins were found exist in the acrosome, nevertheless, only limited attention has been paid to the function of mitochondrial proteins in the acrosome formation.

Rab2 and Rab6 are Implicated in Acrosome Formation during Spermatogenesis in : Based on Sperm Proteome.

Background: Rab proteins are GTP-dependent small proteins that function as regulators of intracellular vesicle transport, fusion, and localization. However, few studies have investigated their function in Decapoda reproduction. The sperm has no tail and the nuclei are uncondensed.
