Alternative Name Caspase-3
Background Caspases are a family of cysteine proteases that are key mediators of programmed cell death or apoptosis (1). The precursor form of all caspases is composed of a prodomain, and large and small catalytic subunits. The active forms of caspases are generated by several stimuli including ligand-receptor interactions, growth factor deprivation and inhibitors of cellular functions. All known caspases require cleavage adjacent to aspartates to liberate one large and one small subunit, which associate into a2b2 tetramer to form the active enzyme. Gene for Caspase-3 also known as Yama, CPP32, and apopain codes for a 32-kDa protein (2-4). Caspase-3 cleaves the death substrate poly(ADP-ribose) polymerase (PARP) to a specific 85 kDa form observed during apoptosis and is inhibitable by the CrmA protein. Other Caspase-3 substrates include DNA-PK, actin, GAS2, and procaspase-6, etc. (5). Caspase-3 is activated by cleavage events at Asp-28/Ser-29 (between N-terminal pro-domain) and Asp-175/Ser-176 (between large and small subunits) to generate a large subunit of 17-kDa and a small subunit of 12-kDa (3). Alternate Names: CASP3, Yama protein, Apopain, CPP32, CPP-32, SCA-1, FocusOn51 , Caspase 3, Cysteine protease CPP32, CASP 3, SREBP cleavage activity 1.
UniProt P42574
Research Area Apoptosis/Necrosis, Autophagy
Application Notes Immunohistochemistry on frozen (ref.6) and paraffin embedded (ref.7) sections. Recommended Positive Control: Staurosporine (2 mM) treated HeLa, Jurkat, Raw, NIH3T3. Western blot: 2-3 ug/ml. Application Notes ABIN121218 detects both pro caspase-3 (~32 kDa) and the large subunit of the active/cleaved form (~14-21 kDa) of Caspase-3. The large subunit of the cleaved form may appear as one or two or even as a stack of bands depending on the presence or absence of the Caspase-3 pro- domain. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user. 1 / 3

anti-Caspase 3, Apoptosis-Related Cysteine Peptidase (CASP3) antibody Western blot analysis for detection of Caspase-3 activation in HeLa cells. Cells were treated with 2 mM staurosporine for different time periods. Caspase-3 activation is determined by cleavage of pro-Caspase-3, which generates 17 and 12 kDa, larger and smaller catalytic subunit, respectively
