The differential expression of 55 genes involved in Ca(2+) signaling highlighted that only ORAI3 expression was significantly altered in smokers (regardless of COPD status). ORAI3 is involved in epithelial cell calcium signaling. ORAI3 is additionally involved in ciliary beating.

Resistance was dependent on external calcium presence and thus Orai3 functionality. This effect allowed a downregulation of the p53 tumor suppressor protein expression via the pro-survival PI3K/Sgk-1/Sek-1 pathway. We demonstrated that p53 degradation occurred not only via Mdm2, but also via another unexpected E3 ubiquitin ligase, Nedd4-2.

miR18a and miR18b positively regulate Orai3 whereas miR34a represses Orai3 expression and function.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
