Calcium Activated Neutral Proteinase is a complex term that refers to a specific enzyme involved in various biological processes. However, for the sake of simplicity, it is beneficial to explore some synonyms that convey the same meaning. One common alternative is Calpain, which encompasses a group of intracellular calcium-dependent proteases. Another synonym is Calcium-activated protease, which highlights the enzyme's dependence on calcium ions for its activation. Additionally, CANP can be shortened to just Calcium Protease, providing a more straightforward way to refer to this proteinase. In essence, these synonyms clearly describe the same enzyme, making it easier to understand its function and significance in different biological systems.
