What is the Difference Between Caspase and Procaspase?
🆚 Go to Comparative Table 🆚The main difference between caspase and procaspase lies in their activity and role in the cell. Here are the key differences:
- Caspase:
- An active protease enzyme necessary for programmed cell death, also known as apoptosis.
- Assists in degrading cellular components through a controlled mechanism, cell proliferation, tumor suppression, and cell differentiation.
- Usually found as monomers or dimers.
- Procaspase:
- An inactive protease enzyme that serves as an inactive precursor of caspase.
- Larger molecule than caspase, typically found as heterodimers or heterotetramers.
- Forms active caspase enzymes after dimerization and cleavage.
In summary, caspases are active protease enzymes involved in apoptosis, while procaspases are inactive precursors that need to be activated through dimerization and cleavage to become active caspases.

Comparative Table: Caspase vs Procaspase
Here is a table summarizing the differences between caspase and procaspase:
| Feature | Caspase | Procaspase |
|---|---|---|
| Description | An active protease enzyme involved in programmed cell death | An inactive protease enzyme that is an inactive precursor of caspase |
| Activity | Active in apoptosis, cell proliferation, tumor suppression, and cell differentiation | Inactive until dimerization and cleavage, then forms active caspase enzymes |
| Size | Relatively smaller molecule | Relatively larger molecule, typically heterodimers or heterotetramers |
| Structure | Monomers or dimers | Monomeric or dimeric |
| Function | Degrading cellular components through a controlled mechanism | Activation requires dimerization and cleavage |
Caspases are active protease enzymes that play a crucial role in programmed cell death, while procaspases are inactive protease enzymes that serve as precursors to caspases. The key distinction between the two is their activity level and the fact that procaspases require dimerization and cleavage to become active caspase enzymes.
