Background

Function
Caspase 7 is an executioner cysteine protease that cleaves after aspartate residues and participates in programmed cell death and inflammation[1][2]. Mechanistically, death receptor and DNA-damage pathways activate caspase 7 through caspase 8 and caspase 9, placing it within apoptosis signaling cascades[1]. In Fas-stimulated Jurkat cells, caspase 8 activates caspase 3 and caspase 7, supporting a branched protease cascade during apoptotic execution[3]. In inflammatory models, caspase 1 inflammasomes activate caspase 7, and caspase 7 can mediate caspase 1-induced apoptosis upstream of caspase 3[1][4]. Disease and model evidence links caspase 7 to endotoxemia resistance in deficient mice, Salmonella-infected macrophages, neuropathic rat spinal cord apoptosis, and CHO-cell viability studies[1][4][5][6]. Compared with caspase 3, caspase 7 shares substrate recognition and some endogenous substrates, but specific substrates, caspase 1-dependent activation, and endotoxemia phenotypes distinguish the isoforms[1]. For experimental applications, isatin sulfonamides inhibit caspases 3 and 7 and serve as PET or SPECT apoptosis-imaging recognition units after radiolabeling[7].

Isoforms & Post-Translational Modification
P55210 has 4 isomers: P55210-1: 34277 Da (predicted); P55210-2: 28030 Da (predicted); P55210-3: 37815 Da (predicted); P55210-4: 31614 Da (predicted).
Cleavage by different proteases, such as granzyme B (GZMB), caspase-1 (CASP1), caspase-8 (CASP8), caspase-9 (CASP9) or caspase-10 (CASP10) generate the two active subunits (PubMed:12824163, PubMed:16352606, PubMed:16916640, PubMed:35338844, PubMed:35446120, PubMed:9852092). Its involvement in different programmed cell death processes is probably specified by the protease that activates CASP7 (PubMed:16916640, PubMed:9852092). Cleaved and activated by initiator caspases (CASP8, CASP9 and/or CASP10), leading to execution phase of apoptosis (PubMed:16352606, PubMed:16916640, PubMed:21555521, PubMed:27889207). Cleavage and maturation by GZMB regulates granzyme-mediated programmed cell death (By similarity). Cleaved and activated by CASP1 in response to bacterial infection (By similarity). Propeptide domains can also be cleaved efficiently by CASP3 (PubMed:8755496). Active heterodimers between the small subunit of caspase-7 and the large subunit of CASP3, and vice versa, also occur (PubMed:8755496). Also cleaved at the N-terminus at alternative sites by CAPN1, leading to its activation (PubMed:19617626);Phosphorylation at Ser-30 and Ser-239 by PAK2 inhibits its activity (PubMed:21555521, PubMed:27889207). Phosphorylation at Ser-30 prevents cleavage and activation by initiator caspase CASP9, while phosphorylation at Ser-239 prevents thiol protease activity by preventing substrate-binding (PubMed:21555521, PubMed:27889207);(Microbial infection) ADP-riboxanation by C.violaceum CopC blocks CASP7 processing, preventing CASP7 activation and ability to recognize and cleave substrates;Ubiquitinated by BIRC6; this activity is inhibited by DIABLO/SMAC -
Subunit
Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 20 kDa (p20) and a 11 kDa (p11) subunit (PubMed:11701129, PubMed:11752425, PubMed:16916640, PubMed:20566630). Interacts with XIAP (via its second BIR domain); inhibiting CASP7 activity (PubMed:11257230, PubMed:11257231, PubMed:16916640). Interacts with BIRC6/bruce (PubMed:15200957). Interacts with ATXN3 (short isoform 1) (PubMed:30455355). Interacts with HSPA5 (PubMed:26045166)
