MSP130-related-2 is thought to play a role in bio-mineralization as revealed in Crassostrea gigas and sea urchins. In this study, an MSP130-related-2 gene was isolated from Hyriopsis cumingii (HcMSP130-related-2) and characterized for the first time. The HcMSP130-related-2 cDNA was 2307 bp in length and consisted of a 572-bp 5'-untranslated region (5'-UTR), a 1239-bp open reading frame encoding 430-amino acid residues, and a 439-bp 3'-UTR.

Molecular characterization and expression patterns of the big defensin gene in freshwater mussel (Hyriopsis cumingii)

G. - L. Wang, Xia, X. - L., Li, X. - L., Dong, S. - J., and Li, J. - L., Molecular characterization and expression patterns of the big defensin gene in freshwater mussel (Hyriopsis cumingii), vol. 13, pp. 704-715, 2014.

Antimicrobial peptides (AMPs), of which big defensins are examples, are an important component of the natural defenses of most living organisms, and possess remarkable microbicidal activities. In the present study, using expressed-sequence tag sequences from a cDNA library and RACE, the full-length cDNA sequence of the big defensin gene from the triangle-shell pearl mussel, Hyriopsis cumingii, (HcBD), was cloned.

Molecular characterization and expression pattern of an α-amylase gene (HcAmy) from the freshwater pearl mussel, Hyriopsis cumingii

G. Ren, Tang, J. Y., and Wang, Y., Molecular characterization and expression pattern of an α-amylase gene (HcAmy) from the freshwater pearl mussel, Hyriopsis cumingii, vol. 13, pp. 6653-6664, 2014.

The freshwater pearl mussel Hyriopsis cumingii is of commercial importance because it produces the freshwater pearl; however, knowledge about the molecular characterization and regulation mechanisms of α-amylase remains unknown for this species. In this study, the full-length cDNA of the α-amylase gene (HcAmy) was isolated from H. cumingii by the rapid amplification of cDNA ends.

Two chitin metabolic enzyme genes from Hyriopsis cumingii: cloning, characterization, and potential functions

G. - L. Wang, Xu, B., Bai, Z. - Y., and Li, J. - L., Two chitin metabolic enzyme genes from Hyriopsis cumingii: cloning, characterization, and potential functions, vol. 11, pp. 4539-4551, 2012.

Chitin, the second most important natural polymer in the world, and its N-deacetylated derivative chitosan are found in a wide variety of organisms. These versatile biopolymers are associated with a broad range of biological functions. This article is the first to report the potential functions of 2 chitin metabolic enzyme genes from Hyriopsis cumingii. A chitinase-3 gene (Chi-3) and a chitin deacetylase gene (Cda) were cloned from H. cumingii and characterized.

Cloning and expression analysis of the 37-kDa laminin receptor precursor gene from Hyriopsis cumingii

X. Z. Chang, Li, J. L., Bai, Z. Y., and Li, X. L., Cloning and expression analysis of the 37-kDa laminin receptor precursor gene from Hyriopsis cumingii, vol. 12, pp. 6130-6139, 2013.

Hyriopsis cumingii is an economically important freshwater pearl mussel with high pearl quality that is endemic in China. Investigation of genes relevant to shell formation is important for increased pearl output. The substances that form mollusk shells are secreted by epithelial cells in the mantle, the proliferation of which influences secretion ability. This study focused on the proliferation-related 37-kDa laminin receptor precursor (37LRP) of H. cumingii. The full-length cDNA (1133 bp) encoding this 300-amino acid protein was cloned from the mantle.
