Mechanism of caspase-2 activation upon DNA damage

Аннотация

The mechanism of caspase-2 activation in response to DNA damage was studied using human ovarian cancer cells Caov-4 treated with chemotherapeutic agent cisplatin. It was shown that mutations of the three cleavage sites of caspase-2 do not affect the assembly of the macromolecular complex of caspase-2 and its activation, but, conversely, stabilize this complex, most likely, via the inhibition of the dissociation of the active caspase-2.
