Target Background

Cysteine protease that plays essential roles in programmed cell death, axonal degeneration, development and innate immunity. During apoptosis, localizes in the nucleus and cleaves the nuclear structural protein NUMA1 and lamin A/LMNA thereby inducing nuclear shrinkage and fragmentation. Furthermore, cleaves many transcription factors such as NF-kappa-B and cAMP response element-binding protein/CREBBP. Cleaves phospholipid scramblase proteins XKR4 and XKR9. Plays an essential role in axon degeneration during axon pruning which is the remodeling of axons during neurogenesis but not apoptosis. Regulates B-cell programs both during early development and after antigen stimulation. In addition, promotes the ZBP1-mediated activation of programmed cell death pathways including pyroptosis, apoptosis, and necroptosis (PANoptosis) and plays an essential role in defense against viruses. Mechanistically, interacts with RIPK3 and enhances the interaction between RIPK3 and ZBP1, leading to ZBP1-mediated inflammasome activation and cell death.
Gene References into Functions
  1. The prodomain region was found to be intrinsically disordered independent of the activation state of caspase-6; however, its complete removal resulted in the protection of the adjacent 26-32 region, suggesting that this region may play a regulatory role. The molecular details of caspase-6 dynamics in solution provide a comprehensive scaffold for strategic design of therapeutic approaches for neurodegenerative disorders. PMID: 28864531
