Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B IP IH IC
RasGAP, a regulator of Ras and Rho, stimulates the GTPase activity of normal RAS p21 but not its oncogenic counterpart. RasGAP is a Caspase 3 substrate (1) and acts as both pro- and anti-apoptotic protein depending on the extent of its cleavage by caspases (2). At low levels of caspase activity, RasGAP is cleaved at position 455, generating an N-terminal fragment (fragment N) and a C-terminal fragment (fragment C). Fragment C alone can induce apoptosis, but this response is completely inhibited by fragment N (3). Fragment N appears to be a general blocker of apoptosis downstream of caspase activation because it inhibits caspase 9-induced cell death. At higher caspase activity, fragment N is further processed and Cleavage of fragment N abrogates its protective functions, and hence the second cleavage of RasGAP promotes apoptosis (4).
