Calpain 2 also known as m-calpain and Calpain 1 known as u-calpain are calcium-dependent non-lysosomal cysteine proteases. They have an approximate mass of 80 kDa for the large catalytic subunit. These proteins exist ubiquitously across various tissues in mammals. Mechanically Calpain 2 and Calpain 1 modulate a multitude of cellular processes by cleaving specific substrates in a calcium-dependent manner. Both require different calcium concentrations for activation with Calpain 2 needing higher levels compared to Calpain 1.
Biological function summary
These calpains play important roles in cytoskeletal remodeling signal transduction and cell cycle progression. They function independently and do not belong to any larger complex. Their ability to specifically cleave substrates means they finely tune cellular functions and contribute to the cell’s response to various stimuli. Misregulation of Calpain activity may lead to developmental abnormalities or disease states reflecting their importance in controlled proteolysis within cells.
Pathways
Calpain 1 and Calpain 2 integrate into the calcium signaling and apoptosis pathways. They can modulate proteins such as the caspase precursors preventing unnecessary cell death and ensuring proper cell cycle regulation. Furthermore Calpain involvement in the Wnt signaling pathway affects cellular processes related to proliferation and differentiation. These interactions demonstrate Calpains’ connections to key cellular processes and how they influence both cell survival and development.
Aberrant Calpain activity is linked to muscular dystrophies and Alzheimer's disease. Overactivation of Calpain can cause excessive proteolysis contributing to muscle tissue degradation in muscular dystrophies. Similarly they may disrupt neuronal stability affecting proteins like tau in Alzheimer's disease which further relates Calpain malfunction to amyloid-beta accumulation. Therefore understanding and potentially modulating Calpain activity are key strategies in the therapeutic targeting of these conditions.
