Supplementary information

Smac/Diablo is a mitochondrial protein that promotes apoptosis by interfering with inhibitor of apoptosis proteins (IAPs). The protein also known as Second Mitochondria-derived Activator of Caspases weighs approximately 27 kDa. Researchers detect Smac/Diablo in various tissues with higher expression levels in organs like the heart and brain. This protein's expression also varies depending on the cell's state and external stimuli.
Biological function summary

Smac/Diablo plays a significant role in programmed cell death by binding to IAPs and negating their inhibition of caspases the key executors of apoptosis. Smac/Diablo releases from mitochondria into the cytosol when apoptotic signals activate. It does not form complexes but interacts with IAPs facilitating the activation of caspases and enhancing the apoptotic response. Its interaction with IAPs highlights its important function in apoptosis regulation.

Pathways

Smac/Diablo integrates into the mitochondrial apoptosis pathway contributing to the intrinsic pathway of apoptosis. It closely interacts with proteins such as caspases and IAPs. This integration is important for apoptosis regulation linking mitochondrial outer membrane permeabilization with the activation of caspases. Additionally the protein engages in the cytochrome c pathway promoting apoptosis by restricting IAPs and aiding in the release of cytochrome c important for apoptosis progression.

Researchers associate Smac/Diablo with cancer and neurodegenerative diseases like Alzheimer's disease. In cancer elevated Smac/Diablo levels can result in increased apoptotic death of cancerous cells potentially serving as a target for therapy. It also interacts with proteins like XIAP in these disease contexts. In neurodegenerative disorders dysregulation of apoptosis pathways involving Smac/Diablo might contribute to excessive neuronal cell death. Understanding Smac/Diablo's role in these diseases provides insights into possible therapeutic interventions.

Target data

Promotes apoptosis by activating caspases in the cytochrome c/Apaf-1/caspase-9 pathway. Acts by opposing the inhibitory activity of inhibitor of apoptosis proteins (IAP). Inhibits the activity of BIRC6/BRUCE by inhibiting its binding to caspases (PubMed : 15200957, PubMed : 36758104, PubMed : 36758105, PubMed : 36758106).. Isoform 3. Attenuates the stability and apoptosis-inhibiting activity of XIAP/BIRC4 by promoting XIAP/BIRC4 ubiquitination and degradation through the ubiquitin-proteasome pathway. Also disrupts XIAP/BIRC4 interacting with processed caspase-9 and promotes caspase-3 activation.. Isoform 1. Defective in the capacity to down-regulate the XIAP/BIRC4 abundance.
