COMMENTARY
LITERATURE
evolution
-
human caspase-10 and caspase-8, EC 3.4.22.61, are highly homologous in their protein sequence, 46% identical in the catalytic domain, and their genes are on the same region of human chromosome 2q33-34 suggesting that they have a common ancestor
evolution
-
initiator and executioner caspases, the pro-apoptotic members of the caspase family are subdivided in the initiators of apoptosis, i.e. caspases-8, -9 and -10 in humans, and the executioners of apoptosis, caspase-3, -6 and -7, phylogenetic tree of all the human caspases, overview. The initiators have a relatively large N-terminal dimerization domain, either a death effector domain, caspases-8 and -10, or a structurally related caspase recruitment domain, caspase-9. Caspase-18 and the ancestor of -8 and -10 called caspase-810 in this schematic are still found in fishes. Later on in evolution, caspase-8 and -10 branched off from caspase-810
malfunction
-
addition of a caspase-10 inhibitor totally blocks PTK7-knockdown-induced apoptosis
malfunction
-
caspase-10 silencing in neuroblastoma is cell-type related. Downregulation of individual or all caspase-10 isoforms in SH-EP cells does not affect TRAIL sensitivity
malfunction
-
mutations or deficiencies in caspase-10 are associated with autoimmune lymphoproliferative syndrome
physiological function
-
caspase-10 activation is important in the initiation phase of apoptosis
physiological function
-
flunarizine triggers apoptosis in Jurkat cells via FADD-independent activation of caspase-10
physiological function
-
activation of caspase-10 in apoptosis is induced by PTK7 knockdown. Caspase-10 may play a critical role in PTK7-knockdown-induced apoptosis, downstream of mitochondria. The intrinsic pathway, i.e. mitochondria pathway, involves a decrease in mitochondrial membrane potential and release of cytochrome, overview
physiological function
-
caspase-10 is an initiator caspase of proinflammatory and apoptotic pathways induced by vaccinia infection. The processing of a short vaccinia virus-encoded antigen can take place by a proteasome-independent pathway involving initiator caspase-5 and -10, which generate antigenic peptides recognized by CD8+ T lymphocytes. Each enzyme can use the degradation products of the other as substrate for new cleavages, indicating concerted endoproteolytic activity of caspase-5 and -10, EC 3.4.22.58 and EC 3.4.22.63
physiological function
-
individual caspase-10 isoforms play distinct and opposing roles in the initiation of death receptor-mediated tumour cell apoptosis in several tumour cell types. Distinct caspase-10 isoforms induce opposed apoptotic signals in NB cells. Isozymes caspase-10A and -10D strongly increase tumour necrosis factor-related apoptosis-inducing ligand, i.e. TRAIL, and FasL sensitivity, whereas caspase-10B or -10G have no effect or are weakly anti-apoptotic. The unique C-terminal end of caspase-10B is responsible for its degradation by the ubiquitin-proteasome pathway and for its lack of pro-apoptotic activity compared with caspase-10A and -10D. Functional comparison to caspase-8, EC 3.4.22.61, overview. Caspase-10A or -10D isoforms can substitute for caspase-8 in the initiation extrinsic apoptosis
physiological function
-
prodeath role for both cleaved and uncleaved caspase-10
metabolism
-
apoptosis is a form of programmed cell death that requires members of a family of aspartate-specific cysteine proteases, called caspases, to both initiate and execute the apoptotic phenotype
additional information
-
isozymes caspase-10B and -10A/B are protected from CHX-mediated degradation by lactacystin treatment
additional information
-
residue D297 is essential for autocleavage, while even though the sequence surrounding D319 is compatible for cleavage by caspase-10, its location close to the compact core makes it unavailable for cleavage
additional information
-
the heterodimer of caspase-10 with FLIPL still can cleave Bid and induce intrinsic apoptosis

no dominant negative effect in co-transfection assay into H9 lymphocytic cell line. Protection from severe disease by caspase-10 V410I in 63 families with autoimmune lymphoproliferative syndrome Ia due to dominant Fas mutation
V410I
-
the mutation in caspase-10, that is associated with autoimmune lymphoproliferative syndrome, ALPS, is a common polymorphism in the healthy Danish population
Y446C
-
no dominant negative effect in co-transfection assay into H9 lymphocytic cell line
L285P
-
the mutation may contribute to the pathogenesis of factions of T-acute lymphoblastic leukemia and multiple myeloma
additional information
-
somatic mutation of caspase-10 is rare in colon, breast, lung, and hepatocellular carcinomas, caspase-10 mutation may contribute to the pathogenesis of some colon carcinomas
additional information
-
caspase-10 isoforms are transiently downregulated using siRNAs targeting all caspase-10 isoforms, or siRNAs specific for individual caspase-10 isoforms. Downregulation of individual or all caspase-10 isoforms in SH-EP cells does not affect TRAIL sensitivity
additional information
-
construction of a truncated mutant lacking the first 202 residues, and of the truncation mutant with a substitution D297A in the catalytic site, cloning into a vector with chimeric protein with an N-terminal His-tag followed by the Fv-domain. Chemically inducible dimerization fusions activate the wild-type but not the cleavage site mutant caspase-10

COMMENTARY
LITERATURE
medicine
-
two patients that are combined heterozygous for single nucleotide substitutions in the Fas and caspase-10 genes. The first patient carries a splice site defect suppressing allele expression in the Fas gene and the P501L substitution in caspase-10. The second has a mutation causing a premature stop codon (Q47X) in the Fas gene and the Y446C substitution in caspase-10. Fas expression is reduced and caspase-10 activity is decreased in both patients. In both patients, the mutations are inherited from distinct healthy parents. Co-transmission of these mutation is responsible for autoimmune lymphoproliferative syndrome
