Gene Regulation
G protein–coupled receptor Gpr115 (Adgrf4) is required for enamel mineralization mediated by ameloblasts
Dental enamel, the hardest tissue in the human body, is derived from dental epithelial cell ameloblast-secreted enamel matrices. Enamel mineralization occurs in a strictly synchronized manner along with ameloblast maturation in association with ion transport and pH balance, and any disruption of these processes results in enamel hypomineralization. G protein–coupled receptors (GPCRs) function as transducers of external signals by activating associated G proteins and regulate cellular physiology.
