詳細 | tetramer according to gel filtration, mass spectrometry, gel electroporesis, literature reports. This structure is of active, cleaved caspase-7. A procaspase-7 dimer becomes active, cleaved caspase-7 upon proteolytic processing, which cleaves after residues D23, D198 and D206. This generates four chains from each monomer. The prodomain (residues 1-23) and the intersubunit linker (residues 199-206) are both released. Thus active, cleaved caspase-7 has two copies of the large subunit (residues 24-198) and two copies of the small subunit (residues 206-303). |
