Calpain 2 also known as CAPN2 or calpain-2 is a heterodimer protease enzyme weighing around 80 kDa. It belongs to the calpain family which requires calcium ions for activation. Calpain 2 expresses in many tissues including the brain muscles and liver indicating its widespread role in cellular processes. The enzyme comprises a large catalytic subunit and a small regulatory subunit each encoded by different genes.
Biological function summary
Calpain-2 plays a significant role in cell signaling cytoskeletal remodeling and apoptosis regulation. It does not typically function in isolation but partners with other molecules forming complexes necessary for precise proteolytic activity. This enzyme modulates several cell functions by cleaving substrates like cytoskeletal proteins transcription factors and enzymes which allows cells to respond adaptively to various stimuli.
Pathways
Calpain-2 integrates into important signaling cascades such as the ERK and PI3K/AKT pathways. It influences these pathways by processing specific proteins and modifying their activity thereby affecting cell survival and proliferation. Calpain-2 closely interacts with proteins like phosphatidylinositol-45-bisphosphate 3-kinase (PI3K) and extracellular signal-regulated kinases (ERKs) within these pathways emphasizing its importance in finely-tuning cellular responses.
Calpain-2 links to several pathological conditions including neurodegenerative diseases like Alzheimer's and muscular disorders such as Duchenne Muscular Dystrophy. In Alzheimer's disease calpain-2 activity influences the processing of amyloid precursor proteins contributing to plaque formation. In Duchenne Muscular Dystrophy calpain-2 activity disrupts muscle fiber integrity through its interaction with proteins like dystrophin aggravating the disorder's progression.
