Expression of genes responsible for biomineralization of Pinctada fucata during development
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2010This study compares the expression levels of nacrein, N16, MSI60, Prismalin-14, aspein and MSI31 genes during the ontogeny of Pinctada fucata. Several novel findings were obtained: 1) The early calcitic prismatic layer was distinguished as a thin membrane-like structure.

Ecological Study on Biomineralization in Pinctada fucata
2018Pinctada fucata inhabits in tropical and subtropical seas, so the sea water conditions have great impacts on its growth and shell formation. To determine the potential effects of global climate change and the water pollution on the oyster growth in the near future, we have conducted a series of studies about the metabolism and shell formation of P ...

A novel nacre protein N19 in the pearl oyster Pinctada fucata
Biochemical and Biophysical Research Communications, 2007A novel 19kDa protein, which was named N19, was isolated from the nacreous layer of the pearl oyster Pinctada fucata. N19 is one of predominant proteins found in the water-insoluble fraction of the nacreous layer. MALDI-TOF/TOF analysis indicated that the three trypsin-digested peptides (791.45, 824.42, and 1118.65m/z) corresponded to the amino acid ...

Microplastics impact shell and pearl biomineralization of the pearl oyster Pinctada fucata
Environmental Pollution, 2022Microplastics are extremely widespread aquatic pollutants that severely detriment marine life. In this study, the influence of microplastics on biomineralization was investigated. For the first time, multiple forms and types of microplastics were detected and isolated from the shells and pearls of Pinctada fucata.

Molecular Basis of Biomineralization in Pinctada fucata
2018Biomineralization is the accumulation and formation of minerals regulated by living organisms transforming into biological structures and tissues. This is an extremely widespread phenomenon since we’ve found many creatures in all six taxonomic kingdoms which could form biominerals, and more than 60 different types of them have been identified, such as ...

Molecular Regulation Mechanism of Biomineralization of Pinctada fucata
2018To elucidate the mechanism of biomineralization in Pinctada fucata, most of the researchers put their attention on the roles of matrix proteins in shell formation. Our group has identified and characterized many essential matrix proteins in the regulation of deposition of calcium carbonate crystals in both prism and nacre layers, as described in the ...

Structural and functional analyses of a TIMP and MMP in the ligament of Pinctada fucata
Journal of Structural Biology, 2017The bivalve hinge ligament is the hard tissue that functions to open and close shells. The ligament contains fibrous structures consisting of aragonite crystals surrounded by a dense organic matrix. This organic matrix may contribute to the formation of fibrous aragonite crystals, but the mechanism underlying this formation remains unclear.

The Study on Enzymes Related to Biomineralization of Pinctada fucata
2018As an efficient, economical, and clean catalyst, enzymes are expected to have novel features. Efforts have been made to screen new enzymes in marine organisms. In our recent studies, we explored the basic characteristics and functions of alkaline phosphatases, acid phosphatases, carbonic anhydrases, tyrosinase, and a novel astacin-like ...

Fish & Shellfish Immunology, 2017
The pearl oyster Pinctada maxima exhibits great difficulty to culture pearls through nuclear insertion with an allograft, but it is easy for P. fucata to culture pearls after allografting. If P. fucata could be used as a surrogate mother to culture P. maxima pearls, it would benefit the pearl culture industry of P. maxima.

Gene cloning and functional study of PmKSPI from Pinctada fucata martensii
Fish & Shellfish Immunology, 2022Kunitz-type serine protease inhibitors (KSPI) are a family of serine protease inhibitors (SPIs) and are extensively found in animals, plants, and microbes. SPI can inhibit proteases that may be harmful or unwanted to its cells. Here, a four-domain Kunitz-type SPI, PmKSPI, was cloned by RACE in the pearl oyster Pinctada fucata martensii. The full-length
