The zebrafish genome contains at least five msx homeobox genes, msxA, msxB, msxC, msxD, and the newly isolated msxE. Although these genes share structural features common to all Msx genes, phylogenetic analyses of protein sequences indicate that the msx genes from zebrafish are not orthologous to the Msx1 and Msx2 genes of mammals, birds, and amphibians.(More)
Pore-forming proteins containing the structurally conserved membrane attack complex/perforin fold play an important role in immunity and host-pathogen interactions. Intermedilysin (ILY) is an archetypal member of a cholesterol-dependent cytolysin subclass that hijacks the complement receptor CD59 to make cytotoxic pores in human cells. ILY directly competes(More)
Bacterial pathogens produce a variety of toxins capable of altering the levels of cAMP in the cells of infected hosts. Moreover, cAMP is an important signaling molecule in many bacterial species, involved in regulation of gene expression in response to a variety of environmental stimuli. The genome of the opportunistic pathogen Pseudomonas aeruginosa(More)
The major proteolytic activity of Trypanosoma cruzi is a cathepsin L-like cysteine protease expressed in all stages of the parasite. As an initial step in identifying possible functions of this enzyme in the life cycle of T. cruzi, and examining its potential as a target for rational drug design, two fluoromethyl ketone-derivatized cysteine protease(More)
