Target Information
Cleaved Caspase-3 is a crucial marker of apoptosis, the programmed cell death process. It is the activated form of Caspase-3, resulting from proteolytic cleavage. Cleaved Caspase-3 plays a vital role in executing apoptosis by cleaving various cellular substrates, leading to cell dismantling. Researchers use Cleaved Caspase-3 as a reliable indicator of apoptosis in studies of cancer, neurodegenerative diseases, and other conditions involving cell death. Its detection is essential for understanding the mechanisms of apoptosis and developing targeted therapies. In cancer research, cleaved Caspase-3 is used to assess the effectiveness of anti-cancer therapies that induce apoptosis in tumor cells. Elevated levels of cleaved Caspase-3 have been associated with better prognosis in certain cancers, such as oral tongue squamous cell carcinoma. Additionally, cleaved Caspase-3 has been implicated in non-apoptotic roles, such as promoting angiogenesis and chemotherapy resistance. Neurodegenerative Diseases: In neurodegenerative diseases like Alzheimer's (AD) and Parkinson's (PD) disease, cleaved Caspase-3 is involved in the apoptotic pathways that lead to neuronal cell death. For instance, caspase-3-cleaved Tau aggregates more easily than full-length Tau, contributing to the pathology of Alzheimer's disease. Understanding the role of cleaved Caspase-3 in these diseases helps researchers develop targeted therapies to mitigate neuronal loss and disease progression.
This product is manufactured by BioVision, an Abcam company and was previously called 3015 Anti-Caspase-3 (Active) Polyclonal Antibody.
Caspases are synthesized as inactive pro-enzymes that are processed to active form in cells undergoing apoptosis. Caspase 3 has been extensively studied and implicated to play an important role in apoptosis. Active caspase 3 proteolytically cleaves and activates other caspases, as well as relevant targets in the cells (e.g., PARP). This affinity purified antibody recognizing the active forms of caspase-3 provides a new tool for identifying apoptotic cell populations in both tissue sections and cultured cells.

The Cleaved Caspase-3 also known as active caspase 3 plays an important role in the execution phase of cell apoptosis. The caspase 3 molecule has a molecular weight of approximately 32 kDa. It undergoes cleavage into subunits that are important for its activation marking its conversion into the cleaved form. Cleaved caspase is widely expressed in various tissues with a notable presence in the cytoplasm of cells undergoing apoptotic processes. Cleavage of caspase 3 results in the formation of a functional enzyme that participates in the degradation of cellular components during apoptosis.
Biological function summary
Caspase 3 acts as an executioner enzyme in the process of programmed cell death. Its cleavage from the inactive zymogen form into the active form triggers apoptotic pathways ensuring the removal of damaged or unnecessary cells. Cleaved caspase operates within a proteolytic cascade often in conjunction with other caspases such as caspase 9. Once activated caspase 3 targets and cleaves specific cellular substrates contributing to the characteristic morphological changes and DNA fragmentation associated with apoptosis.
Pathways
Cleaved caspase 3 is significant within the intrinsic and extrinsic apoptotic pathways. It acts downstream of initiator caspases such as caspase 9 in the intrinsic pathway where its activation involves mitochondrial signals. In the extrinsic pathway it closely associates with caspase 8 mediating cell death signals from extracellular triggers. These pathways ensure that cleaved caspase 3 fulfills its role as a critical mediator of apoptosis linking upstream death signals to cellular dismantling during the apoptosis process.
Cleaved caspase 3 connects to conditions such as cancer and neurodegenerative diseases. In cancer dysregulation of caspase 3 activity may lead to evasion of apoptosis facilitating tumor progression. Therapeutic approaches aim to restore its apoptotic functions in cancer cells. In neurodegenerative diseases like Alzheimer's disease abnormal activation of cleaved caspase 3 contributes to neuronal loss. It interacts with proteins like amyloid precursor protein promoting the pathological changes associated with this disorder. Understanding these interactions provides insights into potential therapeutic avenues.
