Proteolysis of noncollagenous proteins in sea cucumber, Stichopus Japonicus, body wall (sjBW) was investigated. The proteins removed from sjBW by SDS and urea extraction were mainly noncollagenous proteins with molecular weights about 200kDa (Band I) and 44kDa (Band II), respectively. Band I and Band II were identified as major yolk protein (MYP) and actin,(More)
An alkaline phosphatase was purified from the gut of sea cucumber Stichopus japonicus by n-butyl alcohol extract, ammonium sulfate precipitation, ion exchange chromatography with diethylaminoethyl cellulose, gel filtration chromatography with Sephacryl S-200 and preparative electrophoresis with polyacrylamide gel electrophoresis. The native enzyme was(More)
Exosomes are nanosized small membrane microvesicles of endocytic origin secreted by most cell types. Exosomes, through its carrying protein or RNA from derived cells, affect gene regulation networks or epigenetic reorganization of receptor cell, and then modulate the physiological processes of cells. Studies have shown that external exosomes secreted by(More)
