The SpSM30 gene family of the sea urchin, Strongylocentrotus purpuratus, is comprised of six members, designated SpSM30A through SpSM30F (Livingston et al., 2006). The SpSM30 proteins are found uniquely in embryonic and adult mineralized tissues of the sea urchin. Previous studies have revealed that SpSM30 proteins are occluded within the embryonic(More)
Skeleton formation involves secretion of massive amounts of mineral precursor, usually a calcium salt, and matrix proteins, many of which are deposited on, or even occluded within, the mineral. The cell biological underpinnings of this secretion and subsequent assembly of the biomineralized skeletal element is not well understood. We ask here what is the(More)
A central issue in better understanding the process of biomineralization is to elucidate the function of occluded matrix proteins present in mineralized tissues. A potent approach to addressing this issue utilizes specific inhibitors of expression of known genes. Application of antisense oligonucleotides that specifically suppress translation of a given(More)
