Essential mediator of p53/TP53-dependent and p53/TP53- independent apoptosis. Interacts with MCL1 and BCL2A1. Interacts with BCL2 and BCL2L1/BCL-XL. By DNA damage, glucocorticoid treatment, growth factor deprivation and p53/TP53. Ubiquitously expressed. Belongs to the Bcl-2 family. 4 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Mitochondrial
Chromosomal Location of Human Ortholog: 19q13.3-q13.4
Biological Process: caspase activation; release of cytochrome c from mitochondria; positive regulation of protein homooligomerization; apoptosis; release of sequestered calcium ion into cytosol; reduction of endoplasmic reticulum calcium ion concentration; positive regulation of neuron apoptosis; determination of adult life span; response to DNA damage stimulus; negative regulation of growth
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
