Gene Name
STIM1: Stromal interaction molecule 1
Gene ID
6786
General Description
This gene encodes a type 1 transmembrane protein that mediates Ca2+ influx after depletion of intracellular Ca2+ stores by gating of store-operated Ca2+ influx channels (SOCs). It is one of several genes located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region.

Function of the protein in oral and tooth development

In developing mouse teeth at day 11, Wang et al. (2014) found expression of the Stim1 gene in maturation-stage ameloblasts, but not in secretory ameloblasts. Furukawa et al., (2017) generated mice with ectodermal tissue-specific deletion of Stim1, Stim2, and Stim1 and Stim2, and analyzed their enamel phenotypes as compared with those of control animals. In results showed ablation of Stim1 and Stim1/2 but not Stim2 expression resulted in chalky enamel and severe attrition at the incisor tips and molar cusps (Furukawa et al., 2017).
