| Description | multiple isoforms; BH3 only protein (the BH3 domain is essential for proapoptotic function). |
| Expression | wide |
| Localisation | mitochondria |
| Function | BBC3 is transcriptionally induced upon diverse apoptotic stimuli to induce apoptosis via the mitochondrial apoptotic pathway. BBC3 is transcriptionally activated by p53; it is also upregulated after endoplasmic reticulum stress, independantly to P53 status. BBC3 is also transactvated by p73, a p53 related protein with, also, G1 cell cycle arrest and apoptosis functions. BBC3 induces BAX conformational change and multimerization. |
