Plasma-membrane calcium pumps (PMCAs) are responsible for the expulsion of Ca(2+) from the cytosol of all eukaryotic cells and are one of the major transport systems involved in long-term regulation of resting intracellular Ca(2+) concentration. An important feature of stony corals, one of the major groups of calcifying animals, is the...

Bone morphogenetic proteins (BMPs) are members of the transforming growth factor beta superfamily, and have been identified by their ability to induce bone formation in vertebrates. The biomineral-forming process, called biomineralization, is a widespread process, present in all kingdoms of living organisms and among which stony corals are one...

We report here for the first time the isolation and characterization of a protein from the organic matrix (OM) of the sclerites of the alcyonarian, Corallium rubrum. This protein named scleritin is one of the predominant proteins extracted from the EDTA-soluble fraction of the OM. The entire open reading frame (ORF) was obtained by comparing...
