COMMENTARY
LITERATURE
evolution
-
the O-GlcNAc moieties constitute a common epitope between cruzipain and either myosin or other cardiac O-GlcNAc-containing proteins
malfunction
-
cruzain-deficient Trypanosoma cruzi rapidly activates host macrophages via NF-kB P65 and is unable to survive intracellularly within macrophages. No significant IL-12 expression occurs in macrophages infected with wild-type Trypanosoma cruzi and treated with lipopolysacchrides and brefeldin A, confirming impairment of macrophage activation pathways
physiological function
physiological function
-
infection with wild-type parasites appears to induce cruzain-mediated proteolysis of NF-kappaB P65 leading to unresponsiveness of the host macrophage during early 60 min of infection. This immune evasion mechanism may be critical for Trypaosoma cruzi survival during early natural infection with a low number of trypmastigotes. The signaling factor NF-kappaB P65 colocalizes with cruzain on the cell surface of intracellular wild-type parasites, and is proteolytically cleaved. Transcription factor NF-kappaB P65 is translocated to the nucleus and activated only in macrophages infected with cruzain-deficient parasites
physiological function
-
cruzipain promotes Trypanosoma cruzi adhesion to Rhodnius prolixus midgut

substrate specificity of cruzipain 2 isoform is analysed using internally quenched flurogenic substrates. It is found that cruzipain 2 compared to cruzipain differs substantially regarding the specificity in the S2, S1' and S2' pockets, suggesting that cruzipain 2 acts on distinct natural substrates

-
PCZ, is also a good inhibitor of brucipain from Trypanosoma brucei. The propeptide of cruzipain does not inhibit human cathepsins S, K or B or papain at the tested concentrations, and moderately inhibits human cathepsin V. Human cathepsin F is very efficiently inhibited (Ki of 32 picomol/L)

additional information
-
in general immunoglobulin G fractions isolated from rabbits immunised with rabbit apha2-macroglobulin-recombinant catalytic domain of congopain-complexes are the most inhibitory towards the proteolytic activity of congopain. Antibodies produced by rabbits immunised with recombinant catalytic domain of congopain in Freund's adjuvant are generally found to weakly inhibit congopain with a maximum of 40%

glycoprotein
-
single units of O-linked N-acetylglucosamine, usually components of nuclear and cytoplasmatic proteins, are present at the C-terminal domain of cruzipain. They show participation of in the molecular antigenicity of cruzipain. The immune cross-reactivity between cruzipain and myosin, in murine heart tissue, is mainly focused in the C-T domain. The O-GlcNAc moieties constitute a common epitope between cruzipain and either myosin or other cardiac O-GlcNAc-containing proteins

molecular biology
-
in this study it is shown in murine macrophage cell line J774 as well as in murine bone marrow-derived macrophages, that cruzipain induces p38 phosphorylation with Trypanosoma cruzi infection triggering mainly JNK and ERK phosphorylation. Cruzipain also favors the survival in macrophages by changing the iNOS/arginase balance
