Caspase-10 (CASP10) is a cysteine-aspartic protease belonging to the caspase family, which plays critical roles in apoptosis (programmed cell death) and inflammatory signaling. As an initiator caspase, it is activated through dimerization upon apoptotic stimuli, particularly in the extrinsic pathway mediated by death receptors like Fas, TRAIL receptors, and TNF receptors. CASP10 cleaves downstream effector caspases (e.g., caspase-3/7) and cellular substrates, triggering apoptotic cascades. Dysregulation of CASP10 is implicated in diseases such as cancer, autoimmune disorders, and neurodegenerative conditions.
Recombinant CASP10 proteins are engineered for research and therapeutic applications. Produced via heterologous expression systems (e.g., E. coli, mammalian cells), these proteins retain enzymatic activity and structural integrity for functional studies. Researchers utilize recombinant CASP10 to investigate its activation mechanisms, substrate specificity, and interactions with regulatory proteins like FLIP or IAPs. Its role in apoptosis resistance—often observed in cancers—has driven interest in developing CASP10-targeted therapies. Additionally, mutations in CASP10 (e.g., ALPS-type mutations) linked to autoimmune lymphoproliferative syndrome (ALPS) are studied using recombinant variants to dissect genotype-phenotype relationships.
Structural studies of recombinant CASP10. including its prodomain and catalytic subunits, have provided insights into its zymogen activation and substrate recognition. Its recombinant form also serves as a tool for high-throughput drug screening to identify pro-apoptotic compounds or caspase inhibitors. Despite functional overlap with caspase-8. CASP10 exhibits unique regulatory features, making its recombinant version vital for delineating isoform-specific roles in cell death and immune regulation. Ongoing research aims to harness its therapeutic potential in modulating apoptosis-related pathologies.
