Abstract
Sperm proteins play vital roles in fertilization, but little is known about their identities in free-spawning marine invertebrates. Here, 286 sperm proteins are reported from the Hong Kong oyster Crassostrea hongkongensis using label-free and semi-quantitative proteomics. Proteins extracted from three sperm samples are separated by SDS-PAGE, analyzed by LC-MS/MS, and identified using Mascot. Functional classification of the sperm proteome reveals energy metabolism (33%), signaling and binding (23%), and protein synthesis and degradation (12%) as the top functional categories. Comparison of orthologous sperm proteins between C. hongkongensis, Crassostrea gigas, Mytilus edulis, and M. galloprovincialis suggests that energy metabolism (48%) is the most conserved functional group. Sequence alignment of the C. hongkongensis bindin, an acrosomal protein that binds the sperm and the egg, with those of three other Crassostrea species, reveals several conserved motifs. The study has enriched the data of invertebrate sperm proteins and may contribute to studies of mechanisms of fertilization in free-spawning invertebrates. The proteomic data are available in ProteomeXchange with the identifier PXD018255.

Huang X, Huan P, Liu B. A comparative proteomic analysis reveals important proteins for the fertilization and early embryonic development of the oyster Crassostrea gigas. Proteomics 2017; 17.

Abstract
Molluscan development involves important features that are important to understanding not only molluscan ontogeny but also animal evolution. To gain insight into the gamete proteome and protein function in fertilization and early development, we analyzed the proteomes of unfertilized oocytes and early embryos (2/4-cell stage) of the Pacific oyster, Crassostrea gigas. An oocyte reference map containing 116 protein spots, of which 69 were identified, revealed a high abundance of vitellogenin-derived protein spots. The differentially regulated protein spots during fertilization were screened using comparative proteomic approaches. In total, 18 differentially regulated protein spots were screened, and 15 of these were identified and divided into three groups. The proteins belonging to the first group function in energy supply and antioxidation and are proposed to ensure successful fertilization by regulating the levels of adenosine triphosphate, resisting oxidative stress, and preventing polyspermy. The proteins of the second group are associated with protein synthesis and modification, reflecting active protein synthesis after fertilization. The three proteins belonging to the final group are hypothesized to function in the regulation of embryonic development through the establishment of cell polarity and modulation of methylation reactions in nuclei. These results will enhance our knowledge of molluscan fertilization and development.
