| | Stably transfected (by lipofection) living cells U-2 OS (human osteosarcoma) cell line with plasmid producing red fluorescent fusion protein AIFM2-tHcRed. |
| |
| Description | AIFM2 is oxidoreductase of 373 AA lenght. It is predicted to take part in caspase-independent apoptosis similarly to homologous AIFM1 (AIF, PDCD8). AIFM2 is p53-responsive gene and production of AIFM2 was found to be suppressed in many human cancers. |
| Expression | AIFM2 was detected in most healthy tissues in form of two transcripts (1.8 and 4.0 kb). It is highly expressed in heart, moderately in liver and skeletal muscles, and expressed at low levels in placenta, lung, kidney, and pancreas. |
| Localisation | Cytoplasmic side of cellular membranes. |
| Function | Oxidoreductase, that may be important in mediating a TP53/p53-dependent apoptotic response. Predicted to be caspase-independent effector of apoptotic cell death, but not shown by other authors. Function of this protein is thus unknown. |
| Homology | Homologous to AIFM1 (AIF, PDCD8). They share 22% aminoacid identity. It belongs to the FAD-dependent oxidoreductase family. |
| A novel p53-inducible apoptogenic gene, PRG3, encodes a homologue of the apoptosis-inducing factor (AIF). |
