Specification

• Cat. No.: DFFA-4316H
• Description: DFF is a heterodimeric protein of 40kDa (DFFB) and 45kDa (DFFA) subunits. DFFA (DNA fragmentation factor subunit alpha) is the substrate for caspase-3 and triggers DNA fragmentation during apoptosis. DFF is activated once DFFA is cleaved by caspase-3. The cleaved fragments of DFFA detach from DFFB (the active component of DFF), which in turn triggers DNA fragmentation as well as chromatin condensation during apoptosis. Apoptosis is accompanied by shrinkage and fragmentation of the cells and nuclei and degradation of the chromosomal DNA into nucleosomal units. A reduced level of DFFA detected in ovarian endometriosis may be a part of an apoptosis-resistant mechanism enhancing the disease progression. DFFA at chromosome 1 shows rare allelic variants in neuroblastoma tumors.

Q&As

What diseases or conditions are associated with dysregulation or abnormal expression of DFFA, particularly in the context of apoptotic dysfunction?

Dysregulation or abnormal expression of DFFA is associated with various conditions, including cancer and neurodegenerative disorders, highlighting its role in apoptotic dysfunction.

How does DFFA contribute to DNA fragmentation and chromatin condensation during apoptotic cell death?

DFFA contributes to DNA fragmentation and chromatin condensation by being cleaved and activated by caspases, particularly caspase-3, during apoptotic cell death.

In which cellular compartments is DFFA predominantly localized, especially during the initiation of apoptosis?

DFFA is predominantly localized in the nucleus, specifically during the initiation of apoptosis, where it actively participates in chromatin condensation and DNA fragmentation.

Are there therapeutic implications or potential targets related to DFFA in diseases involving apoptotic dysregulation and abnormal cell survival?

There are potential therapeutic implications related to DFFA in diseases involving apoptotic dysregulation and abnormal cell survival, making it a target for drug development.

What is the primary function of DNA Fragmentation Factor Subunit Alpha (DFFA) in cellular processes and apoptosis?

DNA Fragmentation Factor Subunit Alpha (DFFA) plays a crucial role in cellular processes, primarily contributing to the execution of apoptosis and programmed cell death.

How does DFFA participate in regulating the balance between cell survival and programmed cell death in various tissues?

DFFA actively participates in regulating the balance between cell survival and programmed cell death in various tissues, influencing tissue homeostasis.

Are there specific caspases or factors that activate DFFA, influencing its role in the execution phase of apoptosis?

Specific caspases, including caspase-3, activate DFFA, influencing its role in the execution phase of apoptosis and facilitating efficient DNA degradation.
