Calcium-binding kinase that phosphorylates the caseins and several secreted proteins implicated in biomineralization, including the secretory calcium binding phosphoproteins (SCPP). Preferencially phosphorylates its targets within the S-x-E/pS motif.
Protein phosphorylation is a fundamental mechanism regulating nearly every aspect of cellular life. Several secreted proteins are phosphorylated, but the kinases responsible are unknown. We identified a family of atypical protein kinases that localize within the Golgi apparatus and are secreted. Fam20C appears to be the Golgi casein kinase that phosphorylates secretory pathway proteins within S-x-E motifs. Fam20C phosphorylates the caseins and several secreted proteins implicated in biomineralization, including the small integrin-binding ligand, N-linked glycoproteins (SIBLINGs). Consequently, mutations in Fam20C cause an osteosclerotic bone dysplasia in humans known as Raine syndrome. Fam20C is thus a protein kinase dedicated to the phosphorylation of extracellular proteins.
The process whose specific outcome is the formation of dentin, the mineralized tissue that constitutes the major bulk of teeth. Dentin may be one of three types: primary dentin, secondary dentin, and tertiary dentin.
The process in which a relatively unspecialized cell of neural crest origin acquires the specialized features of an odontoblast, a cell on the outer surface of the dental pulp whose biological function is the creation of dentin.
A developmental process, independent of morphogenetic (shape) change, that is required for an osteoclast cell to attain its fully functional state. An osteoclast is a specialized phagocytic cell associated with the absorption and removal of the mineralized matrix of bone tissue, and which typically differentiates from monocytes.
Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving phosphorus or compounds containing phosphorus.
The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton).

Protein involved in the process by which mineral crystals are deposited in an organized fashion in the matrix (either cellular or extracellular) of living organisms. Such process give rise to inorganic-based structures such as bone, tooth, ivory, shells, cuticles, corals or bacterial magnetosomes.
Protein which catalyzes the phosphorylation of serine or threonine residues on target proteins by using ATP as phosphate donor. Such phosphorylation may cause changes in the function of the target protein. Protein kinases share a conserved catalytic core common to both serine/ threonine and tyrosine protein kinases.
A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
