kaspase6

Kaspase6, also known as Caspase-6, is a cysteine-aspartic acid protease that belongs to the caspase family of enzymes. Caspases are crucial mediators of apoptosis, a programmed cell death process vital for maintaining cellular homeostasis and development. Caspase-6 is classified as an executioner caspase, meaning it is activated downstream in the apoptotic pathway and responsible for cleaving various cellular substrates that lead to cell dismantling.

Caspase-6 is produced as an inactive zymogen, or procaspase, which requires cleavage by initiator caspases, such as Caspase-8 or Caspase-9, to become active. Once activated, Caspase-6 participates in degrading structural and regulatory proteins within the cell, contributing to the morphological and biochemical characteristics of apoptosis. Its substrates include nuclear lamins, cytoskeletal components, and other proteins associated with cell integrity.

Beyond its role in apoptosis, Caspase-6 has been linked to neurodegenerative diseases, notably Alzheimer's disease. Evidence suggests that aberrant activation of Caspase-6 can contribute to neuronal apoptosis and the formation of neurofibrillary tangles, characteristic features of Alzheimer's pathology. Consequently, Caspase-6 is a target of interest for therapeutic intervention in neurodegeneration.

Research into Caspase-6 continues to unveil its broader implications in immune responses, tissue remodeling, and cancer. Its activity is tightly regulated within the cell to prevent unwanted cell death, and dysregulation of caspase function can have significant pathological consequences. Understanding the precise mechanisms of Caspase-6 action remains a focus for developing novel treatments for diseases characterized by excessive or insufficient apoptosis.
