Embryonic Demise Caused by Targeted Disruption of a Cysteine Protease Dub-2
BACKGROUND A plethora of biological metabolisms are regulated by the mechanisms of ubiquitination, wherein this process is balanced with the action of deubiquitination system. Dub-2 is an IL-2-inducible, immediate-early gene that encodes a deubiquitinating enzyme with growth regulatory activity. DUB-2 presumably removes ubiquitin from ubiquitin-conjugated target proteins regulating ubiquitin-me...
متن کاملTargeted disruption of Plasmodium falciparum cysteine protease, falcipain 1, reduces oocyst production, not erythrocytic stage growth.
Cysteine proteases are currently targets for drug development in a number of parasitic diseases, including malaria. In Plasmodium falciparum, the parasite responsible for the most virulent form of human malaria, there are four members of the cathepsin L-like family of cysteine proteases. Three of these (falcipains 2A, 2B and 3) are thought to be primarily involved in haemoglobin digestion, wher...
متن کاملGene disruption confirms a critical role for the cysteine protease falcipain-2 in hemoglobin hydrolysis by Plasmodium falciparum.
Erythrocytic malaria parasites degrade hemoglobin in an acidic food vacuole to acquire free amino acids and maintain parasite homeostasis. Hemoglobin hydrolysis appears to be a cooperative process requiring cysteine proteases (falcipains) and aspartic proteases (plasmepsins), but the specific roles of different enzymes in this process are unknown. We previously showed that falcipain-2 is a majo...
متن کاملGeneral Anosmia Caused by a Targeted Disruption of the Mouse Olfactory Cyclic Nucleotide–Gated Cation Channel
Olfactory neurons transduce the binding of odorants into membrane depolarization. Two intracellular messengers, cyclic AMP (cAMP) and inositol trisphosphate (IP3), are thought to mediate this process, with cAMP generating responses to some odorants and IP3 mediating responses to others. cAMP causes membrane depolarization by activating a cation-selective cyclic nucleotide-gated (CNG) channel. W...
متن کاملA chimeric cysteine protease of Plasmodium berghei engineered to resemble the Plasmodium falciparum protease falcipain-2.
The cysteine proteases falcipain-2 and falcipain-3 are hemoglobinases and potential targets for chemotherapy directed against Plasmodium falciparum, the most important human malaria parasite. Most in vivo evaluations of candidate antimalarials are conducted in murine malaria models, and falcipain homologs from rodent malaria parasites differ importantly from falcipain-2 and falcipain-3. We expr...
