| UniProt Protein Function: | PUMA: 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. |
| UniProt Protein Details: | Protein type:Mitochondrial Chromosomal Location of Human Ortholog: 19q13.3-q13.4 Cellular Component: mitochondrial outer membrane; mitochondrion; cytosol Molecular Function:protein binding Biological Process: caspase activation; release of cytochrome c from mitochondria; positive regulation of protein homooligomerization; apoptosis; reduction of endoplasmic reticulum calcium ion concentration; positive regulation of neuron apoptosis; release of sequestered calcium ion into cytosol; determination of adult life span; response to DNA damage stimulus; negative regulation of growth |
| NCBI Summary: | This gene encodes a member of the BCL-2 family of proteins. This family member belongs to the BH3-only pro-apoptotic subclass. The protein cooperates with direct activator proteins to induce mitochondrial outer membrane permeabilization and apoptosis. It can bind to anti-apoptotic Bcl-2 family members to induce mitochondrial dysfunction and caspase activation. Because of its pro-apoptotic role, this gene is a potential drug target for cancer therapy and for tissue injury. Alternative splicing results in multiple transcript variants.
