Belongs to the proteasome subunit p27 family.
Belongs to the bacterial ribosomal protein bL9 family.
Acts as a cysteine protease in controlling programmed cell death (apoptosis) by proteolytically activating or inactivating a wide range of substrates. Component of the egl-1, ced-9, ced-4 and ced-3 apoptotic signaling cascade required for the initiation of programmed cell death in cells fated to die during embryonic and postembryonic development. During oogenesis, required for germline apoptosis downstream of ced-9 and ced-4 but independently of egl-1. By cleaving and activating ced-8, promotes phosphatidylserine exposure on the surface of apoptotic cells; phosphatidylserine is a specific marker only present at the surface of apoptotic cells and acts as a specific signal for engulfment. By cleaving and converting dcr-1 into a deoxyribonuclease (DNase), promotes apoptotic chromosomal DNA fragmentation. By cleaving mitochondrial fission protein drp-1, may regulate the removal of mitochondria during apoptosis. During germline apoptosis, cleaves translation initiation factor ifg-1 (isoform p170) promoting cap-independent translation. During male tail morphogenesis, promotes apoptosis of the tail-spike cell downstream of ced-4 but independently of egl-1 and ced-9. By cleaving cnt-1, prevents the activation of the prosurvival akt-1/2 signaling pathway and thus promotes apoptosis. Downstream of ced-4, may play a role in sex-specific cell apoptosis by cleaving sex-determining protein fem-1. May regulate germline apoptosis in response to DNA damage, probably downstream of let-60/ras and mpk-1 pathway. Cleaves ced-9 in vitro. Cleaves csp-2 isoform b resulting in the removal of the propeptide and the generation of csp-2 subunit p31 in vitro. Independently of its apoptotic role has additional functions. Probably by cleaving and thereby activating actin-severing protein gsnl-1, required for the elimination of transient presynaptic components during larval development downstream of egl-1, ced-9 and ced-4 pathway. Together with ain-1, a component of the miRNA-induced-silencing complex (miRISC), regulates temporal cell fate patterning during larval development. Acts in cell fate patterning by cleaving heterochronic protein lin-28, likely promoting its degradation. Also cleaves heterochronic protein lin-14 and exonuclease disl-2 in vitro. Downstream of calreticulin crt-1 and ced-4 and independently of egl-1 and ced-9, plays a role in the initial steps of axonal regrowth following axotomy. Cleaves 14-3-3-like protein ftt-2, tubulin tbb-2 and calreticulin crt-1 in vitro. Plays also a role in resistance to S.typhimurium-mediated infection.
Autocatalytic cleavage removes the propeptide and generates the catalytic subunit p17 and two non-catalytic subunits p15 and p13; autoproteolysis is induced by ced-4 oligomer. Cleaved by caspase csp-1 probably at Asp-146 and Asp-376.
Octameric ced-4 activates zymogen autoprocessing and enhances activity of processed ced-3. Zymogen autoactivation is inhibited by csp-3. csp-3 has no effect on active ced-3. Zymogen autoactivation is inhibited by csp-2. Inhibited by cysteine protease inhibitor iodoacetic acid (CH3COOI). Inhibited by benzyloxycarbonyl-DEVD-fluoro-methyl ketone (zDEVD-fmk). Inhibited by benzyloxycarbonyl-VAD-fluoro-methyl ketone (zVAD-fmk). Not inhibited by N-[N-(L-3-transcarboxirane-2-carbonyl)-leucyl]-agmatine (E-64) or by the serine and cysteine protease inhibitor L-1-chloro-3-[4-to-osylamido]-7-amino-2-heptanone (TLCK).
The CARD domain is involved in ced-4 binding.
The active form is probably a heterodimer of the p17 subunit with either the p15 or p13 subunit which are all derived from the precursor by autocatalysis. Interacts with octameric ced-4 (two ced-3 zymogens per one ced-4 octamer); the interaction causes the autoproteolytic cleavage and activation of ced-3. Processed ced-3 also interacts with ced-4 octamer to form a stable holoenzyme. Interacts (via large subunit p17) with csp-3; the interaction prevents ced-3 autoactivation and delays ced-4-induced ced-3 processing. Interacts (via large subunit p17 or small subunit p13 or p15) with csp-2; the interaction inhibits ced-3 autoactivation. Interacts (via propeptide) with nucleoporin npp-14; the interaction tethers ced-3 to the nuclear membrane and prevents its autoprocessing in absence of ced-4. Interacts with dct-1. May form a complex composed of ced-3, ced-4 and mac-1.
