TL;DR: In this paper, the cDNA transcripts of prepro GnRH-like peptides from two species of bivalve molluscs, the Yesso scallop Patinopecten yessoensis and the Pacific oyster Crassostrea gigas, were cloned and compared with those from other invertebrates and vertebrates, and determined their sites of expression and biological activity.

A new lysozyme from the eastern oyster, Crassostrea virginica , and a possible evolutionary pathway for i-type lysozymes in bivalves from host defense to digestion

TL;DR: The pattern of molecular evolution accompanying the shift from defensive to digestive function in the i-type lysozymes of bivalves parallels those seen for c- type ly sozymes in mammals and suggests that the lysozyme paralogs that enhance the range of physiological conditions for lyso enzyme activity may provide stepping stones between defensive and digestive forms.
A novel peptidoglycan recognition protein containing a goose-type lysozyme domain from the Pacific oyster, Crassostrea gigas

TL;DR: Results indicate that CgPGRP-L is expressed in hemocytes by bacterial invasion, and then may play roles of a short PGRP and bacterio-lytic lysozyme.

TL;DR: Evidence that one (ER) of these may have a capacity to autoregulate its own expression in the gonadal cells by estrogen (E2) and that this gene is responsive to estrogenic compounds is presented.

Distribution of multiple peptidoglycan recognition proteins in the tissues of Pacific oyster, Crassostrea gigas.
Naoki Itoh,Keisuke G. Takahashi +1 more
TL;DR: The first report of the possibility that bivalve mollusks have PGN recognition systems as suggested by the identification of multiple PGRPs distributed in various tissues is reported, suggesting that they may also function as antimicrobial proteins.
