Description
Description: Caspase-10 is a DED (death effector domain)-containing caspase and functions as an initiator caspase in Fas/TNF induced apoptosis (1). Four isoforms of caspase-10 have been identified: caspase-10a (Mch4), caspase-10b (FLICE2), caspase-10c and caspase-10d. They have the same prodomain but different mature large and small subdomains (2-4). Upon death ligand-receptor binding, caspase-10 is coupled to the multimeric Fas/TNF receptor complex via DED/FADD adaptor interaction (1-4). This complex processes procaspase-10 into a large active fragment and a small fragment. Cleaved caspase-10 further processes other caspase members, including caspase-3 and caspase-7, to initiate a caspase cascade, leading to apoptosis (3-6).
Function: Involved in the activation cascade of caspases responsible for apoptosis execution. Recruited to both Fas-and TNFR-1 receptors in a FADD dependent manner. May participate in the granzyme B apoptotic pathways. Cleaves and activates caspase-3, -4, -6, -7, -8, and-9. Hydrolyzes the small-molecule substrates, Tyr-Val-Ala-Asp-:-AMC and Asp-Glu-Val-Asp-:-AMC.
Subunit Structure: Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 23/17 kDa (p23/17) (depending on the splicing events) and a 12 kDa (p12) subunit (By similarity). Self-associates. Interacts with FADD and CASP8. Found in a Fas signaling complex consisting of FAS, FADD, CASP8 and CASP10. Interacts with RFFL and RNF34; negatively regulate CASP10 through proteasomal degradation. Interacts with RIOK3.
Post-translational Modifications: Cleavage by granzyme B and autocatalytic activity generate the two active subunits.
Similarity: Belongs to the peptidase C14A family
