1 Mechanistically, BBOX1 binds with the calcium channel inositol-1,4,5-trisphosphate receptor type 3 (IP3R3) in an enzymatic-dependent manner and prevents its ubiquitination and proteasomal degradation. Calcium inositol 1,4,5-trisphosphate receptor type 3 Homo sapiens
2 BBOX1 depletion suppresses IP3R3 mediated endoplasmic reticulum calcium release, therefore impairing calcium-dependent energy-generating processes including mitochondrial respiration and mTORC1 mediated glycolysis, which leads to apoptosis and impaired cell cycle progression in TNBC cells. Calcium inositol 1,4,5-trisphosphate receptor type 3 Homo sapiens
3 BBOX1 depletion suppresses IP3R3 mediated endoplasmic reticulum calcium release, therefore impairing calcium-dependent energy-generating processes including mitochondrial respiration and mTORC1 mediated glycolysis, which leads to apoptosis and impaired cell cycle progression in TNBC cells. Calcium inositol 1,4,5-trisphosphate receptor type 3 Homo sapiens
4 Our study highlights the importance of targeting previously uncharacterized BBOX1-IP3R3-calcium oncogenic signaling axis in TNBC. Calcium inositol 1,4,5-trisphosphate receptor type 3 Homo sapiens
