CASP2

(redirected from caspase-2)

CASP2

A gene on chromosome 7q34-q35 that encodes a member of the cysteine-aspartic acid protease (caspase) family of proteins, which mediate apoptosis by proteolysis of specific protein substrates. CASP2 is involved in stress-induced cell death, cell cycle maintenance and tumour suppression.

Molecular pathology
CASP2 is upregulated in neurodegenerative disorders—e.g., Alzheimer's disease, Huntington's disease and temporal lobe epilepsy.

Summary: TEHRAN (FNA)- Researchers have discovered using mice and human clinical specimens that caspase-2, a protein-cleaving enzyme, is a critical driver of non-alcoholic steatohepatitis (NASH), a chronic and aggressive liver condition.
Apoptotic initiators (such as caspase-2, -8, -9, and -10) activate the downstream cascade of necroptosis with the help of the adapter proteins.
Other studies have also revealed the importance of caspase-2 and caspase-6 in causing the death of retinal ganglion cells following optic nerve transections [41-43].
Caspase2 has been reported as an initiator caspase, its role is very special in apoptosis since caspase-2 gene produces several alternative splicing isoforms (Bouchier-Hayes and Green, 2012).
