| Tissue Specificity | Isoform 1: Ubiquitously expressed. |
| Post Translational Modifications | Ubiquitinated by BIRC6.this activity is inhibited by DIABLO/SMAC. Autoproteolytically activated. |
| Function | Isoform 1: Serine protease that shows proteolytic activity against a non-specific substrate beta-casein. Promotes apoptosis by either relieving the inhibition of BIRC proteins on caspases, leading to an increase in caspase activity.or by a BIRC inhibition-independent, caspase-independent and serine protease activity-dependent mechanism. Cleaves BIRC6 and relieves its inhibition on CASP3, CASP7 and CASP9, but it is also prone to inhibition by BIRC6. Cleaves THAP5 and promotes its degradation during apoptosis. Isoform 2: Seems to be proteolytically inactive. |
